biology help please!?

Ok, here's how it works. It seems that you need genotypes. A homozygous trait is a trait that is both dominant and recessive. Therefore, the organism possesses the dominant trait. A heterozygous genotype is always dominant (dominant is dominant over recessive). For example, brown hair (B) is dominant over blond hair (b). a heterozygous person will be Hh, and will have brown hair even though both alleles are present.

What class was this in? What grade level? What text were you using?  I may be able to help you if I know the context in which the question was raised. I have a feeling that I am not getting all the information you had. Please tell me and maybe I can help. I am an old chemist and microbiologist.

The interaction between an organism and its enviroment is dynamic. It is impossible to separate the "nature" from the "nurture" because they are intertwined. Unfortunately, many people including scientists are too caught up in this false dichotomy.

============================================================\nMitosis is a special kind of cell division used by eukaryote cells. You will probably find a series of diagrams in your biology text book to show the stages of mitosis; these are:\n\nprophase \nmetaphase \nanaphase \ntelophase \n============================================================\n============================================================\n2. cell division \n\neukaryotic cell \n\na.

What are the major taxonomic categories that we use to organize all life on earth -- species, genus, family, order, phylum, etc?  How many Kingdoms are there and how are they determined?  Give the full taxonomy for Homo Sapiens.\n\nWhat is DNA?  What is RNA?  Describe the steps of RNA transcription.  What is mitosis?  Decribe the steps of mitosis.  How is this different from mieosis?\n\nWhat is a gene?  What is the difference between phenotype and genotype?  What is a dominant gene?  What is a recessive gene?  Why is a dominant gene dominant?  What are the other kinds of gene relationships (co-dominance, etc.)  \n\nDescribe the Theory of Evolution.  What was the evidence Darwin found to come up with the Theory.  How do species evolve over time?  What is speciation and give three examples of how different species can evolve?  What is mutation?  What other times of gene changes are there that are related to evolutionary development?\n\nWhat is an ecology? What are the various types of relationships between species (predation, parasitism, mutualism, commensalism, etc.) and give examples of each. What sort of defenses do species develop against predation?  What sort of features do predators develop in return?\n\nWhat is reproduction?  What are the different kinds of reproduction?  How does reproduction differ between various plant species?  Between animal species?  What are some examples of (I forget the term but) animal features/behaviors that serve only to help with reproduction?  How do these evolve?\n\nWhat is a bacteria?  What is a virus?  What are the differences between prokaryotes and eukaryotes?  What are the major organs in a prokaryotic cell/organism?  How about a eukaryotic cell/organism?  What do each of these do?

What about the cell nucleus?\n\nWhat is involved in genetic science?  What sorts of things can genetic science do and what are the tools?  What is gene splicing?  What is genotyping and genetic sequencing?  How do these work?\n\nDescribe the major organs and organ systems in the human body.  What is the function of each?  What is the structure of each.  What are some examples of tissue types and how do you recognize them under a microscope?  What are some of the major diseases that humans suffer and what are the symptoms and cures for each?  How is food processed by the digestive system and which food elements are digested in which organs?  What are the more important hormones and neurotransimitters in the human body and what does each do?  \n\nDescribe the different groups of organic molecules important to life -- proteins, carbohydrates, lipids, etc.  What is the molecular structure of each and how are they different?  What is the importance of each and what is their function in the human body?  What is an amino acid?  How many are there, and what do they do?\n\nAnd so much more ... sheesh.

Are the genes linked? I don't have my book with me here.\n\nIf not, mate a male with one of them. Take the male progeny from that mating and cross with the other mutant. Select hermaphrodites from the period of egg laying when the sex ratio is 1:1 (say the second 8-hour period after they're together). Allow these hermaphrodites to self and select double mutants from the progeny. I think this should do it, but you'd better draw it out.\n\nIf they're linked I think it will just be harder to find double mutant progeny in the final stage, again draw it out to check.

The big O.\nWhy?  Read your biology book- it will do you good to put a little effort into answering this question yourself.  That way you might remember the answer when your 6th grade teacher puts this question on your test.
