उत्तर
Sex-linked diseases are more prominent in men because they have less number of genes.
Explanation:
Males are hemizygous (XY) and have only one X chromosome (meaning they have a lesser number of X-linked genes/alleles compared to (XX) females). Because there is no second X chromosome to mask it, a single recessive gene expresses itself fully and causes the disease.
