In anaphase I the sister chromatids remain attached, while in anaphase II the sister chromatids separate.
Anaphase lAnaphase I
a. chromatids do not separate at the centromere in anaphase I. b. centromeres do not exist in anaphase I. c. crossing-over occurs only in anaphase of miitosis
In Prophase I of meiosis, a tetrad is formed between 2 homologous chromosomes and their replicates. Small pieces are exchanged between the chromosomes and the tetrad breaks up. Then things happen as usual. So really the only difference is that there's genetic recombination.
Meiosis I and meiosis II
Meiosis allows a cell to form into 4 cells (by meiosis 1 (which is literally mitosis) and meiosis 2 (mitosis without DNA replication)) in meiosis 1, the cells exchanges DNA information between homologous pairs, this allows genes to be transferred and creates 4 unique and distinct cells. segragation of alleles occur too.
In Anaphase I of meiosis.
Anaphase 1 is the phase in meiosis where homologous chromosomes separate and move to opposite poles of the cell. Anaphase 2, on the other hand, is the phase in meiosis where sister chromatids separate and move to opposite poles of the cell. Essentially, anaphase 1 involves the separation of homologous chromosomes, while anaphase 2 involves the separation of sister chromatids.
Anaphase lAnaphase I
The steps to Meiosis are ;~ Prophase 1~ Metaphase 1~ Anaphase 1~ Telephase 1~ Prophase 2~ Metaphase 2~ Anaphase 2~ Telephase 2
In Anaphase I
they are prophase I, metaphase I, anaphase I and telophaseI. :)
Meiosis 1: Prophase 1, Metaphase1, Anaphase 1, Telophase 1. Meiosis 2: Prophase 1, Metaphase 2, Anaphase 2, Telophase 2. Makes 4 daughter cells that contain 4 chromosomes each.
Interphase Prophase 1 Metaphase 1 Anaphase 1 Telophase 1 Cytokinesis 1 Prophase 2 Metaphase 2 Anaphase 2 Telophase 2 Cytokinesis 2
The tetrads are pulled apart.
Reduction Division
Meiosis consists of two main stages: Meiosis I and Meiosis II. In Meiosis I, homologous chromosomes separate, resulting in two haploid cells. In Meiosis II, sister chromatids separate, resulting in four haploid cells.
one similarity is the chromosomes in both cells line up at the equator before they split, one difference is in meiosis2 the cells split from two cells into four, while in meiosis1 the singular stretches apart and splits to form two new daughter cells.
