I am sooo confused! What is the difference between a & b and c & d? I was reading the lecture and I think I fugred out c & d. So I mainly need help with a & b.
6a. This question is about the haploid sperm and egg cells that the guinee pig can make. Remember our lab where the 2 homologous pairs separate. So you have B which is homologous to B and only one of each is going to end up in each gamete. (the fact that they happen to be the same since the animal is homozygous doesn't matter. ) Same with the R and R. So by separating the 2 B's and the 2 R's so that there is only one B and one R in each sperm, you know what the gamete for the male is. Using that example to figure on what is in the eggs.
OHHH. I see. Your question was about the difference between a and b.... OK I didn't read your question very well. In a and c, Shawn wants a number (how many possibilities?) In b and d she wants you to show what those possibilities are. Yes? I had to read the question twice the first time I saw it. So for question b, following the discussion I gave above, one of those possibilities would be BR . You know how to derive the rest.
Actually 6a-d are really the same concept as problem 1. If you have done problem 1 correctly, you should have no problem with 6 (it is just worded differently.)
I wish I could help!! I am in the same boat!
