Question

human body cells each have 46 chromosomes in their nuclei. meiosis is necessary in order to ensure that each gamete produced in the human body has -

23 chromosomes

92 chromosomes

46 chromosomes

12 chromosomes

Explanation:

Meiosis is a type of cell division that reduces the chromosome number by half. Human body cells (somatic cells) have 46 chromosomes (diploid, 2n). Gametes (sperm or egg cells) are produced via meiosis, so their chromosome number is haploid (n), which is half of 46, i.e., 23 chromosomes. This ensures that when two gametes fuse during fertilization, the resulting zygote has the correct diploid number (46) of chromosomes.

Answer:

A. 23 chromosomes
