Most sex-linked genes are found where

The glucose dehydrogenase gene is located on chromosome 1 in humans. Men and women can get the X-linked ones since both inherit X chromosomes. This explains why women are frequently carriers of X-linked traits but more rarely have them expressed in their own phenotypes.

In women, a recessive allele on one X chromosome is often masked in their phenotype by a dominant normal allele on the other. All of them were men, as expected.

Sex-linked genes could be located on? Most of the Y chromosome genes are involved with essential cell house-keeping activities 16 genes and sperm production 9 gene families. If the gene is recessive, then males only need one such recessive gene to have a sex-linked trait rather than the customary two recessive genes for traits that are not sex-linked. If the Sox9 gene becomes active in an embryo with two X chromosomes, it causes male gonads to form instead of ovaries, and the individual develops into an anatomical male.
