This question follows on the previous question, and it's a similar setup in which we have coat colors and enzymes that are controlled by genes.
00:11
And so let's just quickly write this out.
00:13
We have p0 going to p1, going to p2, and p2 is black, b1 is gray, and p0 is white, and a controls the enzyme.
00:31
Leaves the enzyme that produces gray, b produces the enzyme that bleeds the black.
00:38
And in this version of the question, c, capital c, the dominant allele of c, can inhibit b, right, and prevent it from functioning.
00:48
And then we're interested in, i mean, we're asked about phenotypic segregation.
00:52
So what proportion of the outcomes of the organisms will be black, which will be, how many will be gray, and what proportion will be white? so let's start with black.
01:05
If you remember the previous question, our cross was basically between a triple heterozygote.
01:14
So a big a, little a, big b, little b, little b, big c, little c, cross to itself.
01:23
All right.
01:24
So that's the setup that we have...
