Question

During which phase of spermatogenesis do primordial germ cells undergo repeated mitotic divisions?

Options

• Growth Phase

• Multiplication Phase

• Spermiogenesis Phase

• Maturation Phase

Answer 1

The Multiplication Phase is characterized by repeated mitotic divisions of primordial germ cells (2n) present in the germinal epithelium of the seminiferous tubules. This phase produces a large population of spermatogonia (2n), each containing 46 chromosomes, establishing a continuous supply of male germ cells.
