Answers

Crossing over happens during which phase of meiosis? a. prophase I b. prophase II c. anaphase I d. anaphase II

Crossing over occurs during which phase of my houses. So the first phase and the longest phase of thematic division in, of course, Masses one is the profits one. And so the chromosome crossing over starts at this appropriates. One of mouse is one and it's facilitated by the formation. Off snapped synaptic memo complex. Um And so essentially, though the answer not to die aggress the answer is still going to be profits one off miles this one so liberated up pro Fes one and the corresponding answer choice is a thank you for listening and I hope this helped.

This question is asking about which phase of my oh Cece involves thes separation of homologous chromosomes. Um, so my oh Cece can basically be divided into eight stages. Pro fes meta phase Anna phase and tell phase of my hostess one end of my houses, too. So we'll use a simple example of ah, simple, hypothetical organism that just has one chromosome. So I've drawn a maternal copy of the chromosome here and read and a paternal copy of the chromosome here in blue. So even though I just drew for lines, this is really only one chromosome. But then there the the one chromosome is composed of two homologous chromosomes and each homologous chromosomes. Has an identity has two identical sister chroma tits, so it looks like four lines, but it's really just one chromosome. And then during med, AFI's, uh, what's called a by Vaillant will line up along the metaphysics plate so that's consists of the maternal and paternal chromosomes lining up right in the middle of cell on the meta phase plate and then, during Anna phase with the homologous chromosomes will separate tow opposite poles of the cell. So this is called the reduction division. So a cell goes from being deployed, having two copies of maternal paternal copy of each crime zone down to being happily so the resulting cells, uh, that finally form during tell a phase are now hap Lloyd and have only one other maternal or paternal copy of the crumbs on the divided then in, uh, my house is to, uh this happens for both cells only. Draw one. Let's take the fraternal version. Uh, the chromosome lines up along the metal faceplate, uh, during metaphysics is And then, during an a phase, the two sister chroma Tibbs will separate thio opposite poles of the cell such that the identical daughter cells formed. Inch have ah, one copy of the identical sister chroma tits. So this question is asking, uh, what's Which of these eight stages involves separation of homologous chromosomes. So, uh, my hoses to involves the separation of, uh, sister chroma Tibbs, not homologous chromosomes. Uh, so the correct answer his question is, see, uh, that the homologous chromosomes actually separate during an a phase of my hostess one. So they line up as a 10 triad, uh, or by Vaillant during, uh, Metta phase of my hosts one men during an a phase one they actually begin to separate on. This is called the reduction division. Um, because homologous chromosomes, air separating to form employed, thought herself.

When during mitosis or cells made hap Lloyd so during an A phase one is when we get a half point number, which means that it would be half.

Okay. You want to answer this question. Let's see about my osmosis. Started with homologous chromosomes and it produces First during this one. Just this chromosomes are going to separate. Okay from one set. And then each of these chromosomes are going to are going to produce two from two cells. We are going to be spilled by the center and each primitive. That is now a chromosome is going to get into each chromosome. Interest itself. Okay. In my closest you get one, for example, this the the cell. Okay. That is a byproduct cell. Again, it's going to produce or only this. Okay. It's going to uh, first is going to start like this is a chromosome After the application is going to become like this. And then it's going to produce similar chromosomes similar to this. Okay. This is going to happen in my toes. So you can see here, Okay, what is like what is much more similar to mitosis? This this one or this video? Cisco. Well, this moses too. right? Because you're producing here first, we're producing Dwayne and Dwayne. The dollars are going to be similar to the point. I said in my office one, you have to wing and you have produced two upload cells that are very different to the parental says because crossing over cured. Okay. And in magazines too, you're going to produce a blood cells. Okay, This manifesto. So as you're producing appliances here and also are similar the parental to this parental. And it feels the same. The my taxes is more similar to my house is too Okay. So in the answers, we have profits. one. No profits. To know metaphors one. No metaphors to yes, because we're talking about metaphors in my toes is so option. D is the answer for this question.
