All right, here is the question we are trying to answer these three questions here.
00:06
And so here i have some diagrams drawn to show what the scenario is for some of them.
00:12
So the first one we're looking at agouti mice, which is determined by the big a allele.
00:19
But we also have a caveat in that a little c, a recessive allele, is of a static to the big a gene, resulting in albino mice.
00:27
So here we have two heterozygut and gaute mice being crossed.
00:33
And so we want to look at what the offspring will be.
00:38
And so here i drew a punnant square to show this cross.
00:43
And we can see these are the resulting offspring.
00:45
And so to determine what the phenotype is, we want to look for the big a allele, which is the agouti, versus the little aalel, which is black.
00:53
And here we have three mice that have the big end.
00:57
So those would be agouti, and this little one was black...
