Question

Describe Gonadal sex determination and accessory determination sex in humans

Answer 1

The gonads are used to determine the sex of a person. Primary sex determination in mammals is strictly chromosomal, and it is largely unaffected by the environment. The female is usually XX and the male is XY. At least one X chromosome must be present in every person. Each of the female's eggs has a single X chromosome because she is XX. Because he is XY, the guy can produce two types of sperm.

The gonadal rudiments first develop in the intermediate mesoderm in humans during week 4 and are sexually indifferent until week 7. The gonadal rudiments are paired intermediate mesoderm areas that grow next to the developing kidneys. The genital ridge epithelium makes up the ventral sections of the gonadal rudiments. The genital al ridge epithelium is indifferent during this period.
