Question

SRY is best described in which of the following ways?
A)a gene present on the X chromosome that triggers female development
B)an autosomal gene that is required for the expression of genes on the Y chromosome
C)a gene region present on the Y chromosome that triggers male development
D)an autosomal gene that is required for the expression of genes on the X chromosome
E)a gene required for development, and males or females lacking the gene do not survive past early childhood

Accepted Answer

SRY (Sex-determining Region Y) is a gene region present on the Y chromosome that triggers male development. Its presence initiates the development of male gonads (testes) and the production of male hormones (androgens), which lead to the development of male reproductive organs and secondary sexual characteristics.
