Answer:
The Y chromosome is one of the two sex chromosomes in humans (the other is the X chromosome). ... Sex is determined by the SRY gene, which is responsible for the development of a fetus into a male.

Explanation:
Y is normally the sex-determining chromosome in many species, since it is the presence or absence of Y that typically determines the male or female sex of offspring produced in sexual reproduction. In mammals, the Y chromosome contains the gene SRY, which triggers male development.
