Is the SRY Gene Responsible for Male Development?
Learn how the SRY gene on the Y chromosome determines male sex by initiating testes formation and male differentiation.
Video transcript
The SRY gene is a critical component in determining male sex. Located on the Y chromosome, it initiates the development of male characteristics by stimulating the formation of testes. Without an active SRY gene, an embryo will typically develop female characteristics, regardless of its genetic sex. Thus, the presence of the SRY gene plays a pivotal role in male differentiation.
Questions and answers
What is the role of the SRY gene in sex determination?
The SRY gene, located on the Y chromosome, triggers the formation of testes, leading to male sex differentiation.
Can someone develop male characteristics without the SRY gene?
Typically, without an active SRY gene, an embryo develops female characteristics regardless of having a Y chromosome.
Is the SRY gene found on the X chromosome?
No, the SRY gene is found on the Y chromosome, which is responsible for initiating male development.
