If the litter resulting from the mating of two short-tailed cats contains three kittens without tails, two with long tails and six with short tails, what would be the simplest way of explaining the inheritance of tail length in these cats? What are the genotypes?
Please show me how to do this question because I need to understand it for futur questions like this one

A man and a woman both have normal colour vision, but their daughter has re-green colorblindness, a sex linked recessive trait. The man sues his wife for a divorce on ground of infidelity. Can genetics provide evidence supporting this case? Explain

Please stop asking home work questions. If you want help, give a question, tell us what you think and why and someone can give you opinons of your answers.

Ok, I'll do this one for you, you know how to draw a genetic diagram? Here, you'll need to draw two, one for the case that the genotype of the woman is I^AI^Ohe case where the genotype is I^AI^A

Complete your diagram to find the possible outcomes of the offpring. If you don't understand, post back. :)

Just FYI, these diagrams are called Punnett squares. A quick Google can turn up a lot of resources for them. I think you can use one to answer most of these questions, except for the one with the 3 colored hamsters, in which case I think you just need to apply the equation for Hardy-Weinberg population genetics.

I'm sure the original poster's homework has long since been turned in... but maybe this will help someone in the future.

Actually, I needed to read the question closer... Hardy-Weinberg doesn't come into play in any of the questions. They're all pretty straight forward Mendellian genetics questions.
