Okay, so in this video, we're going to be looking at how we would figure out the genotype of the f1 individuals based off of two parents, which are both homozygous for their alleles.
00:15
So we know that round is dominant to wrinkled.
00:17
So that's where big r round, little r wrinkled comes from.
00:21
And we know that yellow is dominant to green, which is where big y, yellow, little y, green comes from.
00:28
So we know that we have one individual that's homozygous, round and yellow.
00:34
So round, big, r, big r, yellow, big y, big y, because they're homozygous.
00:39
Crossed with an individual that is homozygous wrinkled and green.
00:43
So homozygous wrinkled, little r, little r, homozygous green, little y, little y.
00:47
So when we're setting up our dye hybrid cross, the way that we find out all the possible combinations of allele that offspring could have is by foiling out the chromosomes of the parents.
01:00
So if you foil big r, big y, you get big r, big y.
01:05
Big r, big y, you get big r, big y...
