Question

Both Tim and Jan have a widow's peak (see Module 9.8), but Mike has a straight hairline. What are their genotypes? What is the probability that Tim and Jan's next child will have freckles and a straight hairline?

Accepted Answer

Hello everyone and welcome to today's video. So if crossing two heterosexual parents use 25% homosexuals dominant and 25% homosexuals recessive offspring, which of the following is the correct ratio. Well, we're already given some of these ratios of here, however, let's just set up the pocket square so that we can visualize each of them individually. Let's make the cross between the two heterosexual parents. And once we do that we can see that we're going to get to hetero sagas. One homocide is dominant and one homocide is recessive. So again, one home a cycle is dominant to hurt er ciggies and one homocide goes recessive. So this is going to be one, two and one. This is the issue that we're going to see between or genotype which is going to be represented by answer choice, one homo cycles dominant to heterosexuals and one homocide recessive. I really hope this video helped you and I hope to see you on the next one.
