During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes. … Therefore, each cell has half the number of sister chromatids to separate out as a diploid cell undergoing mitosis.
Does mitosis end with 2 haploid cells?
Both haploid and diploid cells can undergo mitosis. When a haploid cell undergoes mitosis, it produces two genetically identical haploid daughter cells; when a diploid cell undergoes mitosis, it produces two genetically identical diploid daughter cells.
Does DNA copy itself in meiosis 2?
Summary of Meiosis II
DNA replication does NOT occur at the beginning of meiosis II. The sister chromatids are separated, producing 4 genetically different haploid cells.
What is the result of meiosis 2?
The result of meiosis II is the formation of four unique cells, each carrying a new assortment of genes and chromosomes, and each with half the number of original chromosomes.
Why interphase between meiosis I and meiosis II is short?
Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth. Hence between meiosis I and meiosis II , there is no interphase.
In what way is meiosis II similar to mitosis?
The mechanics of meiosis II is similar to mitosis, except that each dividing cell has only one set of homologous chromosomes. Therefore, each cell has half the number of sister chromatids to separate out as a diploid cell undergoing mitosis.
What is the end product of meiosis 2?
Meiosis II resembles a mitotic division, except that the chromosome number has been reduced by half. Thus, the products of meiosis II are four haploid cells that contain a single copy of each chromosome.
