WebApr 22, 2024 · This is the result of DNA replication, followed by crossing over of homologous chromosomes and separation of chromosomes. There are two cell divisions: the parent cell divides once and then each cell produced by this first division divides once. Meiosis is used to produce gametes (sperm and egg cells), the cells of sexual reproduction. Two ... WebA.) DNA is replicated during meiosis II but not during meiosis I. B.) Homologous chromosomes separate during meiosis I; sister chromatids separate during meiosis II. C.) Meiosis I produces diploid cells; meiosis II produces haploid cells. D.) Chromosomes align along the equatorial plane of the cell in meiosis I but not in meiosis II.

Mitosis produces two daughter cells that are identical to the parent cell. If the parent cell is haploid (N), then the daughter cells will be haploid. If the parent cell is diploid, the daughter cells will also be diploid. WebA diploid cell starts with 2N chromosomes and 2X DNA content. After DNA replication, the cells is still genetically diploid (2N chromosome number), but has 4X DNA content because each chromosome has replicated its DNA. Each chromosome now consists of a joined pair of identical sister chromatids. prolog theorem prover
