In sexually reproducing animals, which type of cells undergo meiosis to produce gametes?
A
Mature haploid gametes (sperm and eggs) to increase genetic diversity
B
Diploid germline cells in the gonads (e.g., spermatogonia/oogonia)
C
Somatic body cells, such as skin or muscle cells
D
Red blood cells in the bone marrow during normal cell turnover

Understand the difference between somatic cells and germline cells: Somatic cells make up the body tissues and organs, while germline cells are specialized cells that give rise to gametes.
Recall that meiosis is a special type of cell division that reduces the chromosome number by half, producing haploid cells from diploid cells, which is essential for sexual reproduction.
Identify that gametes (sperm and eggs) are haploid cells produced through meiosis, ensuring genetic diversity and maintaining chromosome number across generations.
Recognize that meiosis occurs specifically in diploid germline cells located in the gonads (testes in males and ovaries in females), such as spermatogonia and oogonia.
Conclude that somatic cells and other cell types like red blood cells do not undergo meiosis; only diploid germline cells in the gonads undergo meiosis to produce gametes.
