Question

In holandric gene on the mammalian Y chromosome that is essential for the development of male characteristic is called the ______ gene?

1) X-linked
2) Y-linked
3) Autosomal
4) Dominant

Answer 1

The gene on the mammalian Y chromosome that is essential for the development of male characteristics is called the SRY (sex-determining region Y) gene. The correct option is 2) Y-linked

Step-by-step explanation:

The gene on the mammalian Y chromosome that is essential for the development of male characteristics is called the SRY (sex-determining region Y) gene.

The Y chromosome contains only a few genes, and the SRY gene is one of them. This gene triggers the embryo to develop into a male, and its presence determines the male sex.

The SRY gene is an example of a Y-linked gene, as it is found exclusively on the Y chromosome and is not present on the X chromosome. The correct option is 2) Y-linked
