Meiosis
Multiple Choice
In humans, meiosis occurs in which type of cell to produce gametes?
A
Somatic cells throughout the body to support growth and tissue repair
B
Germline cells in the gonads (e.g., spermatocytes in testes and oocytes in ovaries)
C
Mature neurons in the central nervous system to generate genetic diversity
D
Red blood cell precursors in the bone marrow to increase oxygen-carrying capacity
Verified step by step guidance1
Step 1: Understand the purpose of meiosis in humans. Meiosis is a specialized type of cell division that reduces the chromosome number by half to produce gametes (sperm and eggs), which are necessary for sexual reproduction.
Step 2: Identify the types of cells in the human body. Somatic cells make up most of the body and undergo mitosis for growth and repair, while germline cells are specialized cells in the gonads that give rise to gametes through meiosis.
Step 3: Recognize that meiosis does not occur in somatic cells, mature neurons, or red blood cell precursors because these cells either divide by mitosis or do not divide at all.
Step 4: Focus on germline cells located in the gonads (testes in males and ovaries in females) as the site where meiosis occurs to produce spermatocytes and oocytes, respectively.
Step 5: Conclude that meiosis occurs specifically in germline cells in the gonads to generate haploid gametes, ensuring genetic diversity and proper chromosome number in offspring.
