NEET BIOLOGY

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: -Meiosis (My-oh’-sis) is the process by which a single diploid cell splits into four haploid cells called gametes in preparation for sexual reproduction of an organism. Recall that a diploid cell contains two nearly-identical copies of each chromosome, one from each parent, called a homologous pair of chromosomes.

Detailed explanation-3: -Telophase II: During telophase II, cell division begins again in each of the two daughter cells, creating 4 daughter cells. Each of these 4 daughter cells contains 23 chromosomes, making them haploid, and none of the 4 is exactly alike (due to crossing over and independent assortment).

Detailed explanation-4: -In meiosis, one diploid cell divides and makes four haploid sex cells. Meiosis occurs only during the formation of sex cells. Meiosis involves two divisions of the nucleus, meiosis I and meiosis II.

Detailed explanation-5: -The parent cell in meiosis starts off as diploid. It replicates its DNA, then undergoes two sets of cell divisions. The first separates homologous chromosomes, and the second separates sister chromatids. Ultimately, this produces four haploid cells that result from meiosis.
