Germline cells in the gonads (e.g., spermatocytes or oocytes)
B
Neurons in the central nervous system
C
Somatic cells such as skin or muscle cells
D
Mature red blood cells (erythrocytes)
검증된 단계별 안내1
Understand the difference between cell types: somatic cells are all body cells except for those involved in reproduction, while germline cells are specialized cells that give rise to gametes.
Recall that meiosis is a type of cell division that reduces the chromosome number by half, producing haploid cells (gametes) from diploid germline cells.
Identify that meiosis occurs specifically in germline cells located in the gonads (testes in males and ovaries in females), where spermatocytes and oocytes develop.
Recognize that neurons, somatic cells like skin or muscle cells, and mature red blood cells do not undergo meiosis; they either do not divide or divide by mitosis only.
Conclude that the cells undergoing meiosis to produce gametes are the germline cells in the gonads, such as spermatocytes and oocytes.
