Hello everyone and welcome to today's video. So which of the following features distinguishes meiosis from mitosis as answer choice. A we have homologous chromosome pairing and crossing over B formation of identical daughter cells. C, condensation of chromosomes D occurs in somatic cells. So we're going to go over each of these answer choices to see what is true about meiosis and what is true about mitosis about each of them. Let's begin by answer choice D we have that it occurs in somatic cells. Well, the somatic cells are going to be the general cells found around our bodies. However, this is only going to be true for mitosis. We know that meiosis is going to occur in germ line cells which are our reproductive cells within our bodies. Therefore, we can cancel it out because this is not a distinct, this is not distinguishing meiosis from mitosis, rather mitosis from meiosis. Moving on, we have C which is the condensation of chromosomes. We know that the condensation of chromosomes is going to happen in both mechanisms. So we can cancel this out. Then we have B which is going to be the formation of identical daughter cells just like this answer. Choice D occurs in somatic cells. This is only going to be true for mitosis. We know that in meiosis, there are processes occurring such as crossing over that allow the exchange of genetic information, creating different daughter cells. But since this is only true for mitosis, we can cancel this out, then we have a which is going to be homologous chromosome pairing and crossing over. But remember when we stated here that crossing over only occurs in meiosis. Well, this is still a true statement. So we can say that this is something that distinguishes eo from mitosis. And it is the fact that in meiosis, we're going to have the this homologous chromosome pairing and crossing over events are going to create these different daughter cells. Therefore, we can highlight answer choice a homologous chromosome pairing and crossing over as the final answer to our question. I really hope it's helped and I hope to see you on the next video.
