Multiple Choice
Meiosis occurs in which type of cell in humans?
A
Red blood cell precursors in bone marrow to increase oxygen-carrying capacity
B
Mature neurons in the central nervous system to replace damaged nerve cells
C
Somatic body cells to produce genetically identical daughter cells for growth and repair
D
Germline cells in the gonads that give rise to gametes (sperm or eggs)
Verified step by step guidance1
Understand the definition of meiosis: Meiosis is a specialized type of cell division that reduces the chromosome number by half, producing four genetically distinct daughter cells called gametes.
Identify the cell types listed in the problem: red blood cell precursors, mature neurons, somatic body cells, and germline cells in the gonads.
Recall the function of each cell type: red blood cell precursors undergo mitosis to increase oxygen-carrying capacity, mature neurons generally do not divide, somatic cells divide by mitosis for growth and repair, and germline cells undergo meiosis to produce gametes.
Recognize that meiosis specifically occurs in germline cells located in the gonads (testes and ovaries) to generate sperm and eggs, which are necessary for sexual reproduction.
Conclude that the correct answer is germline cells in the gonads because meiosis is the process that produces haploid gametes from diploid germline cells.
