It is responsible for determining male sex characteristics, as it contains the SRY gene (Sex-determining Region Y), which triggers male development by initiating the formation of testes.

It has about 55-200 functional genes, many of which are involved in male sex determination and spermatogenesis (the production of sperm). The sex of human…
