Absolutely nothing to do with chromosome count.\n\n>>>> How closely related are humans to apes and \n>>>> other animals?\n\nIt varies depending on the animal obviously. Around 95% relatedness to chimpanzees. Around 92% for gorillas, as little as 80% for orang-utans. It gets progressively less the  more distant the other species are in evolutionary terms.\n\n>>>>How do scientists measure that?\n\nThere are two basic ways. One is to measure the degree of similarity of the genes, that is the functional parts of the DNA. That generally produces figures quite a bit higher than the ones I gave above. The other is to sequence the entire genome, or large stretches of it and compare it that way. Because those long stretches contain non-coding material they are generally more dissimilar between species.\n\n>>>>Are humans related to plants at all?\n\n\nYep. All living things on this planet are related to some degree. IIRC humans share around 15% of their genes with bananas.

a chromatid forms one part of a chromosome after it has coalesced for the process of mitosis or meiosis. during either process, the word "chromosome" indicates a pair of two exactly identical or "sister" chromatids joined at the central point of each chromatid, called the centromere.\n\na chromosome, by definition, has exactly one centromere. thus when sister chromatids are pulled apart by the mitotic spindle during anaphase - that is, when the centromere joining two sister chromatids splits into two centromeres - then each sister chromatid becomes an independent chromosome.\n\nin non-gametic, non-dividing human cells, there are 23 pairs of chromosomes and thus 46 chromatids.

Aneuploidy is a condition in which the number of chromosomes is abnormal due to extra or missing chromosomes, in other words, it is a chromosomal state where the number of chromosomes is not a multiple of the haploid set. Normal diploid species have 2n chromosomes, where n is the number in the haploid set. Aneuploid individuals would have 2n-1 chromosomes (monosomy), 2n+1 chromosomes (trisomy), or some other such arrangement.\n\nA change in the number of chromosomes can lead to a chromosomal disorder. Aneuploidy is common in cancerous cells.\n\nMonosomy\nMonosomy is the presence of only one chromosome from a pair in a cell's nucleus. Partial monosomy occurs when only a portion of the chromosome has one copy, while the rest has two copies.\n\nHuman genetic disorders arising from monosomy are:\n\nX0-Only one X chromosome instead of the usual two (XX) seen in a normal female, also known as Turner syndrome \ncri du chat syndrome -- a partial monosomy caused by a deletion of the end of the short p (from the word petit, French for small) arm of chromosome 5 \n1p36 Deletion Syndrome -- a partial monosomy caused by a deletion at the end of the short p arm of chromosome 1 \n\nTrisomy\nA trisomy is the presence of three, instead of the normal two, chromosomes of a particular numbered type in an organism. Thus the presence of an extra chromosome 21 is called trisomy 21. Most trisomies, like most other abnormalities in chromosome number, result in distinctive birth defects. Many trisomies result in miscarriage or death at an early age.\n\nA partial trisomy occurs when part of an extra chromosome is attached to one of the other chromosomes, or if one of the chromosomes has two copies of part of its chromosome. A mosaic trisomy is a condition where extra chromosomal material exists in only some of the organism's cells.\n\nA trisomy can occur with any chromosome. Most trisomies result in spontaneous abortion; the most common types that survive to birth in humans are:\n\nTrisomy 21 (Down syndrome) \nTrisomy 18 (Edwards syndrome) \nTrisomy 13 (Patau syndrome) \nTrisomy 9 \nTrisomy 8 (Warkany syndrome 2) \nTrisomy 16 is the most common trisomy in humans, occurring in more than 1% of pregnancies. This condition, however, usually results in spontaneous miscarriage in the first trimester.\n\nTrisomy involving sex chromosomes in humans includes:\n\nXXX (Triple X syndrome) \nXXY (Klinefelter's syndrome) \nXYY (XYY syndrome) \n\nhope this helps

Congenital lack of growth hormone causes extremely short stature and is the most "typical" cause of "dwarfness". \n\nHowever, several other conditions may cause short stature, including precocious puberty and several congenital anomalies (e.g. Turner syndrome).

It depends on the type of cellular reproduction. If the new cell is produced by mitosis then there would be 52 chromosomes because it would be a diploid cell as well. But if the new cell is produced by meiosis then there would be 26 chromosomes because it would be a haploid cell.

Turner syndrome encompasses several chromosomal abnormalities, of which monosomy X, is the most common. It occurs in 1 out of every 2,500 female births. Instead of the normal XX sex chromosomes for a female, only one X chromosome is present and fully functional. This is called 45,X or 45,X0, although other genetic variants occur. In Turner syndrome, female sexual characteristics are present but underdeveloped.\nclick here:http://en.wikipedia.org/wiki/Turner_syndrome#Symptoms

A human somatic cell is a "body cell" (not one involved in sexual reproduction). Therefore, there are 46 chromosomes in a somatic cell. This is also the diploid number. Since we have two sets of chromosomes (one comes from mom and one from dad), we say algebraically that the diploid number = 2n = 46 (in humans). Therefore a haploid set = n = 23 in humans (this would apply to sperm and eggs).

half a chromosome, a chromatid.

the ploidy no is 2n\nbut the dna amount is double. it changes in the metaphase or late prophase

In every cell of the human body there are 46 chromosomes: 44 somatic coding chromosomes (body coding) and 2 sex chromosomes.\n\nEach chromosome is part of a pair.  Each one of the pair codes for the same thing, though not necessarily the identical way (for example, one of the set may code for blue eyes, one may code for brown eyes). \n\nThe idea of homologous pairs is important during meiosis, when the chromosomes replicate, and find their homologous pairing, forming a tetrad (a structure with 4 chromatids from the joining of 2 replicated homologous chromosomes).\n\nHope this helps.

none\n\n\nyou start with one pair of homologous chromosomes in prophase I of meiosis I.  at metaphase I, these homologues line up across the metaphase plate, and at anaphase, they seperate so that one homologue goes to one pole, and the other homologue goes to the other pole.  after cytokinesis at the end of telophase I, you have one homologue in each cell...that homologue then goes through meiosis II, and at metaphase II, that homologue lines up at the metaphase plate with each sister chromatid facing each pole, and the chromosome is "pulled apart".  Anaphase II pulls the sister chromatids to each pole, and cytokinesis splits the one cell into two....two cells, each containing one sister chromatid of a homologous pair. (although in some text books this is refered to as a single homologue)

Midget is the "offensive" term for little people or dwarf.  And yes, just because they are smaller proportioned, doesn't mean that their female parts don't work the same.  They can have children and do have children just like the rest of the human race.

There is no way to prevent dwarfism.  It is in the genes and you can't change your genes.

C... a boy would have XY chromosomes and a female would have XX chromosomes.  Y is always smaller than X.

According to the Little People of America the human definition of dwarfism is "a medical or genetic condition that usually results in an adult height of 4'10" (147 cm) or shorter, among both men and women, although in some cases a person with a dwarfing condition may be slightly taller than that."

First of all we have 23 pairs of chromosomes (or 46 chromosomes), and monkeys have  22 pairs of chromosomes. Big deal right? WRONG. When humans make gametes (sperm and egg) each gamete contains a one copy of the hosts DNA, therefore each gamate only contains 23 chromosomes. When the sperm reaches the egg they combine together (zygote) to from a cell that has 46 chromosomes. Any deviation from this number makes the an embryo inviable. ( we wont get into ploidy or trisomys here). Therefore if a human and an ape mated, the chromosome count coming from the human would be 23 and the money would be 22 making the chimera have 45 chromosomes. First of all essential genetic coding inforemation is lost. (AN ENTIRE CHROMOSOME IS MISSING), you have changed the specie. You have created an alleuploidy. (only viable with some plants). The chromosomes in each species are of different sizes. This totaly screws up the cellular functions and inhibits a proteins job. They would not be able to reproduce. And please do not get me started on Mullers moprhs in terms of loss of genetic information, regarding epistasis, incomplete dominance etc.... All you need to know is it would be inviable because the chromosomes are of different numbers, and the chromsome sizes are different.
