Genetics Problem I

Post by bionewbie » Wed Jan 25, 2006 4:20 am

Hi, I'm just confused as to how to solve this genetics problem:

Q) How many different gametic genotypes can be produced by a diploid genotype AabbCcDDEeFFGg assuming that there are not linkages?

Is the answer 16?

How would the question be different if we were finding the number of different genotypes in the F1 generation resulting from a hybrid cross AaBbCcDd x AaBBccDd?

(1) 16 genotypes for gamets. Shortcut = 2^n; n = heterozygous
(2) 36 genotypes for F1. Shortcut = "analogy" ---> I want to tell you but it is too complicated to type, if you really need I will scan my handwriting for this 8)

Actually for these shortcuts, I kept trying to create a formula by myself and well, it works well... :)

I wouldn't mind if you scan it to me. You can PM me if that is easier ... Thanks!
