Exam 2: Spermatogensis

Step 1: These are diploid (2n)

Spermatogonium

Process 1: Mitosis

A type of cell division where a single diploid cell divides into two identical diploid daughter cells.

Step 2: These are diploid (2n) cells

Primary spermatocyte

Process 2: The separation of homologous chromosomes

Meiosis I

Step 3: These are haploid (1n) cells formed after Meiosis I from a primary spermatocyte.

Secondary spermatocyte

Process 3: This is the second round of meiotic division, where sister chromatids separate, and divides into two haploid spermatids, resulting in four haploid cells

Meiosis II

Step 4: These are haploid (1n) cells

Spermatid

Step 5: This is the final stage

Spermiogenesis

Step 6: These are the mature, haploid male gametes
