Genetically normal humans have 42 autosomes.

Spermatogenesis in human males takes place in the gonads.

In oogenesis, one initial diploid cell in the form of an oogonium will give rise to four functional ova.

The secondary spermatocytes are diploid cells.

The primary oocytes are diploid cells in females in which the number is fixed during birth.

The follicle-stimulating hormones act during the infancy stage to allow the primary oocytes to start undergoing meiotic division.

During puberty of females, the oogenic cells are arrested at the secondary oocyte stage, and only penetration by the sperm cell will allow the continuation of the meiotic division.

Polar bodies are functional cells that provide nourishment to the developing ovum.

The Sertoli cells are the cells of the seminiferous tubules that provides nourishment to the developing sperm cell.

Spermatogenesis can also occur in females.

Gametogenesis involves meiosis.

The number of chromosomes contributed to the offspring by the parents in humans are in equal amounts.

It is possible for oocytes to mature without FSH.

A male organism’s Y chromosome has no homologue.
