Determining potential gametes in a polyhybrid cross

Post by emilycw23 » Fri Jan 23, 2009 7:29 am

I have a question that I can't seem to find help with anywhere. Yes it is a homework question but I am capable of answering most questions myself, this one however, seems to allude me. There are two individuals with the following hypothetical traits A, B, D, G. Individual 1: AabbDdGg and Individual 2: aaBbDdgg. I don't exactly understand how you determine the potential gametes and how you would set them up on a Punnett Square (I realize it will be a very large one). I have heard of the FOIL method but I guess the explanation was not enough for me. Any help would be appreciated, thanks very much!

(A+B)^2 = AA +2AB +BB
If you know multiplication that's foiling.
