Meiosis does the following picture show Anaphase I, Anaphase II. Therefore ,Anaphase I, Anaphase II is correct .
Anaphase I and Anaphase II are distinct stages in the process of meiosis, each playing a crucial role in reducing the chromosome number and ensuring genetic diversity in sexual reproduction.
Anaphase I is a key event in meiosis I, following the completion of prophase I, metaphase I, and the preceding stages.
During Anaphase I, homologous chromosomes, consisting of paternal and maternal chromatids, are separated and pulled towards opposite poles of the cell.
This segregation ensures that each daughter cell receives a unique combination of chromosomes, contributing to genetic diversity.
Unlike in mitosis, where sister chromatids separate, in Anaphase I, it is the homologous chromosomes that move apart.
Anaphase II, on the other hand, occurs in meiosis II, which follows meiosis I.
This stage involves the separation of sister chromatids.
The cells produced during meiosis I undergo further division to produce four haploid cells.
In Anaphase II, the spindle fibers contract, pulling the sister chromatids apart, and ensuring that each resulting gamete receives one chromatid from each chromosome.
This process maintains the halved chromosome number, essential for the formation of gametes with genetic diversity.
Anaphase I separates homologous chromosomes, while Anaphase II separates sister chromatids, collectively contributing to the overall reduction in chromosome number and the creation of genetically diverse haploid cells during meiosis.
