Question

Mating between a male donkey (2n=62) and a female horse (2n=64) produces sterile mules. Recently, however, a very rare event occurred—a female mule gave birth to an offspring by mating with a horse.

Why is it very unlikely that the offspring will have fully horse-like genetic characteristics?

Accepted Answer

Hello, everyone and welcome to today's video. So which of the following statements regarding polo is going to be true? Now, as answer choice, A we have polyploid when an organism's nucleus contains three or more sets of chromosomes. As answer choice. B we have out of polyploid or polyploid whose carty is made up of chromosomes from a single species. As answer choice C we have a low polyploid or polyploid. The chromosome sets from two or more species. And as answer choice D we have all of the above. Let's analyze each of our answer choices so that we may come up with the right answer. So let's begin by answer choice. A. Now remember that polyploid is defined as the presence of three or more sets of chromosomes in an organism's nucleus. So this is correct as a result. Now, this can occur for when complete sets of chromosomes are going to be duplicated or when sets of chromosomes from different species are combined. So these are some of the cases where we can obtain polyploid or remember that as we go over answer choices. Now let's move on to answer choice. B, we have auto polyploid or polyploid whose stereotype is made up of chromosomes from a single species. Well, the prefix I would always going to mean this self polyploid, this polyploid that's within are species which can result from the number of chromosomes being duplicated, which is our first example. Therefore, this is going to be correct as well and we're not going to cancel it out and then we have C which is all polyploid or polyploid with chromosome sets from two or more species. And this is our second example, when different species combine their, their chromosomes, we're going to have the creation of these allo polyploid. So this is also going to be correct. Therefore, since we're not, we were not able to cancel out any of our answer choices or correct answer choice is going to be the all of the above. I really hope this video helped you and I hope to see you on the next one.
