In what type of cell does meiosis occur in humans?
A
Neurons in the central nervous system to increase cell number
B
Mature red blood cells circulating in the bloodstream
C
Somatic body cells to support growth and tissue repair
D
Germline cells in the gonads that give rise to gametes (sperm or eggs)
검증된 단계별 안내1
Understand that meiosis is a specialized type of cell division that reduces the chromosome number by half, producing haploid cells called gametes.
Recognize that meiosis does not occur in somatic (body) cells, which divide by mitosis to support growth and tissue repair.
Note that mature red blood cells lack nuclei and do not undergo cell division, so meiosis cannot occur in them.
Identify that neurons in the central nervous system are generally non-dividing cells and do not undergo meiosis.
Conclude that meiosis occurs specifically in germline cells located in the gonads (testes in males and ovaries in females), which produce sperm and eggs, respectively.
