Super powers.  http://www.goats.com/archive/990903.html\n\nIt also seems noteworthy that sometimes the person remembered for a thing isn't the first person to think of it, but the person who figured out a catchy way to remember it or teach it.  A great modern example would be Richard Feynman teaching introductory physics, or Steve Jobs stealing Xerox's GUI.

not an exact science. has to do with dominant and recessive genes. which ever the genes fit together will determine the output. Like Punnet Squares. Could be shorter, in the middle, or taller than both of you.

fairy tales? , probably you can do that in literature or history, but in physics is sort of hard ..He dedicated his life to work , he was truly a genius, we needed a bunch of scientists to get together just for continue with his legacy ; maybe his ideas were , at his time, sort of fantastic ; but I don't think He was a lier or something ,if that's what you were trying to say... if not, yeah he was fun :P

Mendel's law of dominance\nIn a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype. \n[edit]\nMendel's law of segregation\n \nFigure 3 : The color alleles of Mirabilis jalapa are not dominant or recessive.\n(1) Parental generation. (2) F1 generation. (3) F2 generation. The "red" and "white" allele together make a "pink" phenotype, resulting in a 1:2:1 ratio of red:pink:white in the F2 generation. \nFigure 1 : Dominant and recessive phenotypes.\n(1) Parental generation. (2) F1 generation. (3) F2 generation. Dominant (red) and recessive (white) phenotype look alike in the F1 (first) generation and show a 3:1 ratio in the F2 (second) generationMendel's law of segregation, also known as Mendel's first law, essentially has four parts.\n\nAlternative versions of genes account for variations in inherited characters. This is the concept of alleles. Alleles are different versions of genes that impart the same characteristic. Each human has a gene that controls eye color, but there are variations among these genes in accordance with the specific color the gene "codes" for. \nFor each characteristic, an organism inherits two genes, one from each parent. This means that when somatic cells are produced from two gametes, one allele comes from the mother, one from the father. These alleles may be the same (true-breeding organisms, e.g. ww and rr in Fig. 3), or different (hybrids, e.g. wr in Fig. 3). \nIf the two alleles differ, then one, the dominant allele, is fully expressed in the organism's appearance; the other, the recessive allele, has no noticeable effect on the organism's appearance. In other words, the dominant allele is expressed in the phenotype of the organism. However this does not always hold true: Today, we know several examples that disprove this "law", e.g. Mirabilis jalapa, the "Japanese wonder flower" (Fig. 3). This is called incomplete dominance. There is also codominance on a molecular level, e.g. people with sickle cell anemia, when normal and sickle-shaped red blood cells mix and prevent malaria. \nThe two genes for each character segregate during gamete production. This is the last part of Mendel's generalization. The two alleles of the organism are separated into different gametes, ensuring variation. \nDuring his experiments, Mendel encountered some traits that did not follow the laws he had encountered. These traits did not appear independently, but always together with at least one other trait. Mendel could not explain what happened and chose not to mention it in his work. Today, we know that these traits are linked on the same chromosome.\n\n[edit]\nMendel's law of independent assortment\nAlso known as Mendel's Second Law \nThe most important principle of Mendel's law of independent assortment is that the emergence of one trait will not affect the emergence of another. While his experiments with mixing one trait always resulted in a 3:1 ratio (Fig. 1) between dominant and recessive phenotypes, his experiments with mixing two traits showed 9:3:3:1 ratios (Fig. 2). Mendel concluded that each organism carries two sets of information about its phenotype. If the two sets differ on the same phenotype, one of them dominates the other. That way, information can be passed on through the generations, even if the phenotype is not expressed (F1 generations, figures 1 and 2).\n\nMendel's findings allowed other scientists to simplify the emergence of traits to mathematical probability. A large portion of Mendel's findings can be traced to his choice to start his experiments only with true breeding plants. He also only measured absolute characteristics such as color, shape, and position of the offspring. His data was expressed numerically and subjected to statistical

How about the guys and girl that discovered the structure of DNA?? James Watson, Francis Crick, Rosalind Franklin, and Wilklins. Def all born after 1800 and made a HUUUGGGE impact in life, genome, and life. OR the guy who disocvered penecillin...there are a lot.

I don't like your teacher.  I think he/she is looking for B. genes, but then he/she should not have put chromosomes as an alternative choice.  Mendel's theory of independent assortment was only true because the genes he studied were on separate chromosomes.  It could be argued that what he was actually studying was chromosomal inheritance.

There is no way that Darwin could have been aware of the specific molecule we call deoxyribonucleic acid (DNA). In the mid-eighteenhundreds Friedrich Miescher isolated "nuclein" and then purified it.  The substance was identified as an acid and named as such the same century.  It wasn't until 1929 that the components of DNA were identified and 1937 that an x-ray structure of the polymer was available.  Many people worked at solving the problem (an x-ray structure of a molecule isn't a real "map" like you might think of with bones, its more like a series of clues from which you might "back out" the structure with much difficulty) and in 1953 James Watson & Francis Crick published the seminal Nature paper detailing their proposed structure for DNA, a double-helix with a phosphate backbone and nucleoside interior having set "patterns" of left-right pairing.  \n\nThis was almost 100 years after Charles Darwin published Origin of Species (1859).  Darwin's proposal of evolutionary processes stemmed from observations of the macroscopic natural world and was based not on chemistry but primarily on phylogeny.  Darwin's concepts were utilitarian-based similar to Lamarck's proposals, but differed by rejecting inheritability of aquired characteristics, instead favoring a model where beneficial intrinsic characteristics would arise on their own but predispose their bearers for greater survival & reproduction.  \n\nA contemporary with Gregor Mendel, at the time he wrote his famous Origin of Species, Darwin was not aware of the work of Mendel on inheritance of traits.  However, both scientists' work supported the same conclusions.

what Mendel gave us was the "Law of Independent Assortment" and the "Law of Random Segregation".  Basically, that chromosomes behave in an independent manner when segregating from each other. (ie-when chromosomes are segregated to your gametes, the chromosomes your father gave you will not all go together, they will act independently of each other.)\nIn short, he gave us a way to predict what ratios of progeny to expect from parental generations. \n\nFor example, a dihybrid cross between PPSS and ppss will result in all F1 progeny PpSs, and if intercrossed, those F1 progeny will produce F2 progeny in a 9:3:3:1 ratio....\nso on and so forth.\n\nOf course these principles don't really apply with more complex human genetics...

This is pasage of biblography of my project\n\nGregor Mendel (1822-1884)\nSeung Yon Rhee \n--------------------------------------------------------------------------------\n\nThe theories of heredity attributed to Gregor Mendel, based on his work with pea plants, are well known to students of biology. But his work was so brilliant and unprecedented at the time it appeared that it took thirty-four years for the rest of the scientific community to catch up to it. The short monograph, Experiments with Plant Hybrids, in which Mendel described how traits were inherited, has become one of the most enduring and influential publications in the history of science. \n\nMendel, the first person to trace the characteristics of successive generations of a living thing, was not a world-renowned scientist of his day. Rather, he was an Augustinian monk who taught natural science to high school students. He was the second child of Anton and Rosine Mendel, farmers in Brunn, Moravia. Mendel's brilliant performance at school as a youngster encouraged his family to support his pursuit of a higher education, but their resources were limited, so Mendel entered an Augustinian monastery, continuing his education and starting his teaching career. \n\nMendel's attraction to research was based on his love of nature. He was not only interested in plants, but also in meteorology and theories of evolution. Mendel often wondered how plants obtained atypical characteristics. On one of his frequent walks around the monastery, he found an atypical variety of an ornamental plant. He took it and planted it next to the typical variety. He grew their progeny side by side to see if there would be any approximation of the traits passed on to the next generation. This experiment was "designed to support or to illustrate Lamarck's views concerning the influence of environment upon plants." He found that the plants' respective offspring retained the essential traits of the parents, and therefore were not influenced by the environment. This simple test gave birth to the idea of heredity. \n\nMendel's research reflected his personality. Once he crossed peas and mice of different varieties "for the fun of the thing," and the phenomena of dominance and segregation "forced themselves upon notice." He saw that the traits were inherited in certain numerical ratios. He then came up with the idea of dominance and segregation of genes and set out to test it in peas. It took seven years to cross and score the plants to the thousand to prove the laws of inheritance! From his studies, Mendel derived certain basic laws of heredity: hereditary factors do not combine, but are passed intact; each member of the parental generation transmits only half of its hereditary factors to each offspring (with certain factors "dominant" over others); and different offspring of the same parents receive different sets of hereditary factors. Mendel's work became the foundation for modern genetics. \n\nThe impact of genetic theory is no longer questioned in anyone's mind. Many diseases are known to be inherited, and pedigrees are typically traced to determine the probability of passing along an hereditary disease. Plants are now designed in laboratories to exhibit desired characteristics. The practical result of Mendel's research is that it not only changed the way we perceive the world, but also the way we live in it. \n\nI Hope u get ur answer for more halp contect on don_turtel@yahoo.com Whish u all the bet for homework-project

He is also called Carl Linne. He was a Swedish scientist and he invented the classification of animals and plants that is still in usage in the 18th century. This is what I remember right now but you can learn more about him if you look up his name in an encyclopaedia or on Wikipedia.

In the 1860s, German medical researcher Friedrich Miescher joined Felix Hoppe-Seyler’s laboratory at the University of Tubingen, Germany. There, at a time when scientists were still debating the concept of a “cell”, Hoppe-Seyler’s lab was isolating the very molecules that make up cells. \n\nMiescher was given the task of researching the composition of lymphoid cells -- white blood cells. These cells were difficult to extract from the lymph glands, but could be gathered in great quantities with the pus from infections. So Miescher collected bandages from a nearby clinic and washed off the pus. He experimented and isolated a new molecule – a white, slightly acidic substance he called nuclein. Isolated from the cell nucleus, nuclein – which was later purified to DNA -- was rich in nitrogen and phosphorus, as well as containing carbon, hydrogen, and oxygen. \n\nMiescher’s paper on nuclein was not published until 1871, two years after his discovery. Hoppe-Seyler, sceptical because nuclein was such a unusual molecule, confirmed the results by repeating all the experiments himself.
