What is the cell division during which the chromosome number is reduced from diploid to haploid known as?
A. Meiosis.
B. Mitosis.
C. Hypnosis.
D. Karyokinesis.
Meiosis occurs during the formation of eggs or sperm, where a pair of cell divisions result in gametes with only half the number of chromosomes (haploid) as the other cells of the body. When two gametes unite in fertilization, the fusion of their nuclei reconstitutes the diploid number of chromosomes.
