Answer:

Genes present on the X chromosome are X-linked. These genes have different inheritance patterns because they have different numbers in males (XY) and females (XX).

X-linked genetic diseases are much common in males than in females due to the unique X-linked inheritance pattern.

A human male has two different sex chromosomes, the X and the Y. The X and Y don’t have the same genes and aren’t homologous.

Because sex chromosomes don’t come in homologous pairs always, the genes they show unique, different patterns of inheritance.

Hence, they are different in numbers in male and female lead them a different type of inheritance than others.
