Which event occurs during meiosis II but not during meiosis I quizlet?

What event happens in meiosis II but not in meiosis I?

In meiosis II, these chromosomes are further separated into sister chromatids. Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.

Which event occurs during meiosis I but normally not during mitosis or meiosis II?

The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred. The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.

What event occurs during meiosis I and meiosis II quizlet?

In meiosis I, homologous chromosomes separate resulting in a reduction of ploidy. Each daughter cell has only 1 set of chromosomes. Meiosis II, splits the sister chromatids apart.

What is the difference between meiosis I and 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 event happens in meiosis 2 but not in meiosis 1 quizlet?

Cytokinesis occurs during meiosis II but not meiosis I.

Which of the following occurs during meiosis I but not during mitosis?

Explanation: Crossing over is the only answer choice that does not occur during mitosis. Crossing over occurs during prophase I of meiosis and involves swapping of genetic information between homologous chromosomes. This require the formation of tetrads, which does not occur during mitosis.

Which process normally occurs during meiosis but not during mitosis?

In meiosis , synapsis ( Pairing of homologous chromosome ) , Crossing over ( exchange of chromosomal segment between nos sister chromatids ) occurs which does not occur in mitosis.

What event occurs in meiosis 1?

In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis.

What events occur during each phase of meiosis?

Major Events in Meiosis

Stage Major Events
Anaphase I Two chromosomes of each with two chromatids of each homologous pair separate and move toward opposite poles.
Telophase I Chromosomes arrives at the spindle poles
Cytokinesis Cytoplasm divides to produce two cells, each having half the original number of chromosomes
