Question

the total number of chromosomes present in a human muscle cell is 46. the total number of chromosomes present in a human egg or sperm cell is 23. by which process does the number of chromosomes present in a human egg or sperm cell halve?
fertilization
meiosis
mitosis
regeneration

Explanation:

Meiosis is a type of cell - division that reduces the chromosome number by half, producing gametes (sperm and egg cells). Fertilization combines gametes and restores the full chromosome number. Mitosis produces genetically identical cells with the same chromosome number as the parent cell. Regeneration is the process of regrowing lost or damaged body parts.

Answer:

B. meiosis
