Meiosis
Multiple Choice
In which type of cell does meiosis occur in animals?
A
Fully differentiated neurons in the central nervous system
B
Germline cells in the gonads that give rise to gametes
C
Mature red blood cells (erythrocytes) circulating in the bloodstream
D
Somatic (body) cells throughout the organism for growth and tissue repair
Verified step by step guidance1
Understand the purpose of meiosis: Meiosis is a specialized type of cell division that reduces the chromosome number by half to produce gametes (sperm and eggs) for sexual reproduction.
Identify the cell types listed: Fully differentiated neurons, mature red blood cells, somatic cells, and germline cells in the gonads.
Recall that fully differentiated neurons and mature red blood cells do not divide or undergo meiosis; neurons are post-mitotic, and red blood cells lack nuclei.
Recognize that somatic cells divide by mitosis for growth and repair, not meiosis.
Conclude that meiosis occurs specifically in germline cells located in the gonads, which produce gametes necessary for reproduction.
