The probability that the son of a woman with an autosomal recessive condition is a heterozygous carrier

Accepted Answer

Hi, everyone. Welcome back. Let's look at our next question. It says, if upon constructing the pedigree, you found out that males of every generation have the genetic condition while the females are unaffected, the genetic condition is most likely. Well, we're working through a pedigree pedigree problem trying to figure out how conditions inherited. There are two main questions that we always start with and the first one would be are males and females equally affected. And that of course, helps us distinguish between autism away and sex linked traits. The second question we ask is, does it skip generations? And that helps us distinguish between dominant or recessive conditions. So, in this case, right away, we see that males and females are not equally affected, the males of every generation are affected while none of the females are. So we can go ahead and rule out and we look at our answer choices. Choice. A autism will dominant and choice be autism or recessive. We know we don't have an autism aly inherited condition. Now we need to look at excellent versus Y linked. Well, we see males being more affected, which is a trait. We do see an excellent recessive conditions since males only have one X chromosome. But in this case, it mentions that males of every single generation have the condition when we have excellent traits. Um there can be no father to son inheritance. Since males only pass a Y chromosome to their offspring, you cannot pass a condition from male to male if it's on the X chromosome. So in this case, we can eliminate choice C X linked due to the fact that we do see father to send transmission in this pedigree. So our answer choices indeed choice. The why linked no females are affected because they have no Y chromosome. But every male, males in every generation are affected. Since in each case, males inherit the Y chromosome from their father. So if the conditions carried on the Y chromosome, they only inherit one, why they will always inherit the affected chromosome. See you in the next video.
