Question

The accompanying pedigree shows a family in which one child (II-1) has an autosomal recessive condition. On the basis of this fact alone, provide the following information.

Using A for the dominant allele and a for the recessive allele, give the genotypes for I-1, I-2, and II-1. <>

Accepted Answer

Hello, everyone and welcome to today's video. So the pre degree shown below illustrates how an auto como recessive disease is passed down via a family. Now, which of the following statements best describes the genetic condition of the parents depicted in the pedigree. Well, remember that here we have both parents because they're not shaded black. This means that neither of the parents is affected by this out of como recessive disease. So we're going to write that down. However, since the disease is recessive, this means that they could still carry the a legal for the disease without being affected by they could be head arose a guess. Now, let's set up upon a square to visualize what would happen if both parents are heterosexual for these autism, a recessive disease. And here we can do that. Let's label the disease as disease A or gene A. So if both parents are heterosexuals, the punnett square is going to look just like this. As we can see, the presence of two heterocyclic organism is going to yield a 1/4 probability of having this oughta xoma recessive disease in the offspring. If we look at the offspring or the second generation, we can see that in fact, only one out of four kids or offspring of these parents are going to have the disease. That means that both parents are unaffected carriers of the disease. Now going over answer choices, we can see that the correct answer choice here is going to be answer choice. Both parents are unaffected carriers of the disease or in order words, their hetero Vegas for the A Leo's that carry the disease. I really hope this video helped you and I hope to see you on the next one.
