Understanding why this disparity exists requires a closer look at the genetics involved, the mechanisms of inheritance, and specific. Why are sex linked traits more common in males Why are x chromosomes more common in males than in females The female has two x chromosomes and the male has one x and one y.only one x gene is active in the female The other is inactivated and shows as a barr body. Whereas in the case of males… the allele present on x chromosome will be directly expressed whether it is recessive or dominant.because males have only one x chromosome
Thus x linked traits are more frequently expressed in males than in the females. Because males and females have different combinations of sex chromosomes, the inheritance patterns for these traits differ from autosomal traits This size difference means that many more traits and disorders are linked to the x chromosome, making it a crucial player in sex linked inheritance For example, conditions like duchenne muscular dystrophy and hemophilia are caused by mutations in genes located on the x chromosome, affecting males far more frequently than females. In contrast, females have two x chromosomes and require two copies of a recessive allele to express the trait
