Detailed explanation-1: -The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Detailed explanation-2: -What happens during meiosis II? During meiosis II, the two cells once again cycle through four phases of division.
Detailed explanation-3: -In contrast, meiosis consists of two nuclear divisions resulting in four nuclei that are usually partitioned into four new haploid daughter cells. The nuclei resulting from meiosis are not genetically identical and they contain one chromosome set only.
Detailed explanation-4: -Two nuclear divisions occur during meiosis: meiosis I and meiosis II. Meiosis reduces chromosome number and introduces genetic variations in offsprings.
Detailed explanation-5: -In meiosis II, the sister chromatids separate, making haploid cells with non-duplicated chromosomes.
