Question

Does the mother or father determine the sex of the
offspring? What is the SRY gene?

Answer 1

Neither parent is fully responsible for determining the sex of the baby. However, all eggs produced by the female have an x sex chromosome, and all sperm from the male have either an x or y chromosome sex-determining region y protein, or testis-determining factor, is a dna-binding protein encoded by the sry gene that is responsible for the initiation of male sex determination

Answer 2

Answer Yes

Step-by-step explanation:

In mammals, including humans, the father's contribution determines the sex of the offspring. The mother always contributes an X chromosome, while the father can contribute either an X or a Y chromosome. If the father's sperm carries an X chromosome, the resulting offspring will be female (XX), and if the sperm carries a Y chromosome, the offspring will be male (XY).

The SRY gene, which stands for Sex-determining Region Y, is a gene found on the Y chromosome. It plays a critical role in initiating the development of male characteristics in mammals. The presence of the SRY gene triggers a cascade of genetic and hormonal events during early embryonic development, leading to the development of male gonads (testes) instead of female gonads (ovaries). The testes then produce testosterone and other hormones that drive the development of male reproductive organs and secondary sexual characteristics. If the SRY gene is absent or non-functional, the default pathway in development leads to the formation of female reproductive structures.
