what is the difference between anaphase i and anaphase ii of meiosis?
65154
The main difference between anaphase I and anaphase II is that anaphase I occurs in a diploid cell and anaphase II occurs in a haploid cell. ... In anaphase I, splitting of centromere do not occur whereas, in anaphase II, sister chromatids separate, splitting the centromere.

However, Meiosis I begins with one diploid parent cell and ends with two haploid daughter cells, halving the number of chromosomes in each cell. Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.

What is the difference between Metaphase 1 and Metaphase 2? In Metaphase I, the 'pairs of chromosomes' are arranged on the Metaphase plate while, in the Metaphase II, the 'chromosomes' are arranged on the metaphase plate. In Metaphase I, the spindle fibers get attached to two centromeres of each homologous chromosome.

The difference is that in Metaphase-1 of meiosis the chromosome arrange in two pair wise (synapsis) and therfore cross over takes place while in mitosis the chromosome arrange in single pair and no cross over takes place.
434905
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I.

Concept 12: Meiosis II: Anaphase II. The centromeres separate and the sister chromatids—now individual chromosomes—move toward the opposite poles of the cell. ... The centromeres separate, and the two chromatids of each chromosome move to opposite poles on the spindle.
1146068
Anaphase I: Homologues separate to opposite ends of the cell. Sister chromatids stay together. Telophase I: Newly forming cells are haploid, n = 2. Each chromosome still has two sister chromatids, but the chromatids of each chromosome are no longer identical to each other.
1162375
During mitotic anaphase, centromeres split and the sister chromatids separate and move to opposite poles of the cell to become daughter chromosomes. Anaphase I of meiosis: There are a total of 96 chromatids in 48 chromosomes; each pole has 24 chromosomes/48 chromatids.

What is a major difference between mitosis and meiosis I in a diploid organism? Sister chromatids separate in mitosis, while homologous pairs of chromosomes separate in meiosis I. ... haploid, and the chromosomes are each composed of two chromatids.
740780
Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. ... 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.
158372
During which phase of meiosis do homologous chromosomes separate? Homologous chromosomes separate during anaphase I. Sister chromatids separate during anaphase II.
1168631
Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis II. During anaphase of both meiosis I and meiosis II, the DNA content (number of copies of chromosomes) in a cell is halved. However, the ploidy level changes only when the number of unique chromosome sets in the cell changes.
179624
Pairing of homologous chromosomes begins in prophase I of meiosis, and homologous chromosomes will remain paired until anaphase I. During which phase of meiosis do homologous chromosomes separate? Homologous chromosomes separate during anaphase I. Sister chromatids separate during anaphase II.
109995
In anaphase I, centromeres break down and homologous chromosomes separate. In telophase I, chromosomes move to opposite poles; during cytokinesis the cell separates into two haploid cells.
1378311
In meiosis II, the sister chromatids separate, making haploid cells with non-duplicated chromosomes. Prophase II: Starting cells are the haploid cells made in meiosis I. Chromosomes condense. ... Anaphase II: Sister chromatids separate to opposite ends of the cell.
970491
Homologous chromosomes are separated during anaphase of meiosis I. When are chromatids separated? Chromatids are separated during anaphase of meiosis II.

In Metaphase I, the 'pairs of chromosomes' are arranged on the Metaphase plate while, in the Metaphase II, the 'chromosomes' are arranged on the metaphase plate. In Metaphase I, the spindle fibers get attached to two centromeres of each homologous chromosome.
