WebThe testis-determining gene is the Y-linked gene responsible for initiatingthe developmental pathway leading to testis formation in males. A strategy basedon determining the precise chromosomal location of this locus has been used toclone a new gene which has been called SRY in humans (Sry in mice). A varietyof studies now show that this is indeed the … SRY may have arisen from a gene duplication of the X chromosome bound gene SOX3, a member of the Sox family. This duplication occurred after the split between monotremes and therians. Monotremes lack SRY and some of their sex chromosomes share homology with bird sex chromosomes. SRY is a quickly evolving gene, and its regulation has been difficult to study because sex determination is not a highly conserved phenomenon within the animal kingdom. E… WebIn response to either the presence or absence of a specific stimulus, a signal is sent to the brain that triggers the hypothalamus to secrete either a releasing hormone or an inhibitory hormone.
