Question

In fruit flies, the genes for wing shape and body stripes are linked. In a fly whose genotype is WwSs, W is linked to S, and w is linked to s. Show how this fly can produce gametes containing four different combinations of alleles. Which are parental-type gametes? Which are recombinant gametes? How are the recombinants produced?

Accepted Answer

Hello everyone and welcome to today's video. So today we need to suppose that we have a homo sickles, tall P. So this is going to be homo cycles. Toppy cross with a Homocide short P. Or homo cycles. Recess. City will be the resulting phenotype of the four offspring. In order to do this, we need a punnett square. So let's set that up here. We have it. So we have the homicide was dominant on top and the homicide was recessive at the bottom. If we combine them, we're going to see that we're going to have all of our F. One organisms be hetero sagas. So they have one dominant a leo and one recessive elio. However, since they have a dominant a leo that's the phenotype that is going to be shown. Well a dominant a leo is going to be coding for a tall P. So we're going to have four tall piece. And this is going to be represented by answer choice. C. I really hope this video helped you and I hope to see you on the next one.
