For questions $10-13$ , match the statements that follow to the items in the key. Answers may be used more than once, and more than one answer may be used.
Key:
a. mitosis
b. meiosis
c. meiosis II
d. Both meiosis I and meiosis Il are correct.
e. All of these are correct.
Nondisjunction may occur, causing abnormal gametes to form.

Yeah. In this question, we will compare my toe, sis to my Oh, sis, to match this statement to the correct item in the key. My toe Sis and my oh sis are similar in that they're both orderly Siris of stages that include pro fes pro meta phase meta phase and tell a phase. However, the function between my toe sis and my oh sis and an organism is very different. Might Asus, shown on the right side of the screen, maintains a chromosome number between the cells. Yeah, yeah. Shown in this diagram, the parent cell has four chromosomes and the daughter cells each have four chromosomes. Shown on the left side of the screen is my oasis, which is often referred to as production division. It is referred to as reduction division because my Asus create cells that are destined to become gametes or reproductive cells. This reduction in chromosome number is crucial. Without it, the Union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes. Yeah, as shown in the diagram to the left. The parent cell starts with four chromosomes while each of the four daughter cells have Onley two chromosomes, referring back to the statement in the question. My toe sis would further represent the statement because because the parent cell and the daughter cells have identical chromosome numbers.

Okay. So from 22 here is about these or to kind of cells we have. So they're somatic cells, which are sort of our body cells. Race lose. They're going to be our skin cells. And our liver cells are muscle cells. Then there's the Grammys, and these are considered our sex sells. Right. So this is going to be yours. Berm and ovary. Okay. And so what do we know about them? All the somatic cells contain continue for copy of DNA. Okay. What? And then the gammy, it's sort of contain 1/2 copyright because, uh, when we add them together two you get to two half copies during reproduction, uh, to give you one full copy of DNA. Right? That would give you your side goat, so to speak. Okay, but so we consider the GAM needs to come to be was called a hap Lloyd. Okay, so they are hap Lloyd, and this is a term you'll want to know Hap Lloyd containing containing and chromosomes. All right. And so for humans, that number happens to be for humans. It's 23. Okay, But we just say and so that you can be sort of species generic. All right, so a if we combined two guineas, if we have a somatic cell, which is gonna be was called a was deployed. Okay, so this is a deployed another eternal wants us. We didn't know the sort of implies that it has double the copies of the DNA. Right, cause we mean come over here when we have two of these GAM ease to get one full copy. That gives us two times in because it's beautiful. Copy the D N A rights. That's where this to end comes from. And so in humans and right, if if our end is 23 then are to end is 46 okay, different chromosomes and the deployed cells. So? So we can then look at our choices here and see that somatic cells have 46 chromosomes and the gametes will have half a cz many. So the correct answer is a

So this question is asking which of the following stages involves pairing of duplicated homologous chromosomes s what I've drawn here are the stages of my hostess. So my hostess one pro fes meta phase anna phase tell a phase and my house is too pro fes medicated to enter phase Tell a phase again. Um, and my hostess one involves what's called a reduction division or, ah, separation of homologous chrome Selves. So during pro fes wth e chromosomes condense and this scenario there's actually the chromosome number is actually only one. But for each chromosome or the one chromosome that there is, there's a maternal and paternal home look. And then each of the home logs have been duplicated such that there are two chroma tits. So you see four lines here, but it's actually only one chromosome with two, uh, homologous chromosomes, each composed to cram it. It's now my hostess. One is unique in that during med afis, the, uh duplicated homologous chromosomes line up along the meta face plate and what's called a by Vaillant or a 10 Tran. And this Onley occurs, um, in throughout Myers, this one. This does not occur during my house is too warm. I Oh, cece. Um, because this is the on Lee. My house is one of the only time when you separate homologous chromosomes to form hap Lloyd daughter sense during both my hoses to end my toe. Sis, what lines up along the meta face plate? Our individual duplicated chromosomes, each composed of two primitives and the identical chroma Tibbs are what, uh, separate two opposite poles of the cell, not different chromosomes. So the correct answer to this question is, um, being that the pairing of duplicated homologous chromosomes Onley occurs in my house. This one as I've drawn here during metaphysics stage. Uh, because Thies this formation of Abi Vaillant is getting ready for the reduction division that's unique to my house, this one.

Hello, everyone. Today we will be discussing some differences between my Telesis and made aosis. And the difference is that I'm going to review are the ones that applied on Lee Toe my oasis empty. And these differences are that patriots are present. Another difference is that in my oasis produces four daughter cells. Another difference is that in my oasis, uh, this process reduces the chromosomal numbers by half. And another difference is that in my oh sis synapses and crossing over off Hama logs occurred.
