What is the difference between metaphase I and metaphase II of meiosis quizlet?
Describe the main difference between Metaphase 1 and Metaphase 2. In Metaphase 1, paired homologous chromosomes line up along the equator of the cell. However, in mitosis and Metaphase 2, it is sister chromatids that line up along the equator of the cell. … It is a regular mitosis when chromosomes are not duplicated.
How would you differentiate between a cell in metaphase of mitosis metaphase I and metaphase II?
Hint: Meta means second and phase means stage, hence metaphase is the second stage of meiosis and mitosis.
Distinguish between metaphase of mitosis and metaphase I of meiosis.
|Metaphase of mitosis||Metaphase I of meiosis|
|Individual chromosome align at metaphase plate||Tetrad of chromosomes lie at the metaphase plate.|
What is the difference between meiosis I and meiosis II quizlet?
Meiosis I is a reduction division where only one member of a homologous pair enters each daughter cell which becomes halploid. Meiosis II only splits up sister chromatids.
Which of the following distinguishes metaphase I from metaphase II?
Which of the following distinguishes metaphase I from metaphase II? Metaphase I occurs when homologous chromosome pairs align on the metaphase plate. Metaphase II has sister chromatids of chromosomes aligned at the metaphase plate. Single-celled organisms, like amoebas, reproduce by mitosis.
What is the main difference between metaphase 1 and metaphase 11?
In metaphase I, the homologous pairs of chromosomes align on either side of the equatorial plate. Each daughter cell is haploid and has only one set of chromosomes, or half the total number of chromosomes of the original cell. Meiosis II is a mitotic division of each of the haploid cells produced in meiosis I.
What has happened to the chromosomes between prophase 1 and metaphase 1?
Between prophase I and metaphase I, the pairs of homologous chromosome form tetrads. Within the tetrad, any pair of chromatid arms can overlap and fuse in a process called crossing-over or recombination. Recombination is a process that breaks, recombines and rejoins sections of DNA to produce new combinations of genes.
What is metaphase II?
Metaphase II is the second stage in meiosis II. … The cell is in metaphase II when the chromosomes align themselves along the metaphase plate through the facilitation of the spindle fibers. The spindle fibers are now attached to the two kinetochores contained in the centromere of each chromosome.
How are the chromosomes in a cell at metaphase of mitosis similar to and different from the chromosomes in a cell at metaphase of meiosis II?
There are 23 pairs of chromosomes and two sets. … Compare the chromosomes in a cell at metaphase of mitosis with those in a cell at metaphase of meiosis II. The chromosomes are similar in that each is composed of two sister chromatids, and the individual chromosomes are positioned similarly at the metaphase plate.
