Question
why do males get more sex linked disorders over females
type your answer...
hint: look at the sex chromosomes
Most sex-linked disorders are carried on the X chromosome. Males have one X and one Y chromosome (XY), so if their single X chromosome carries the recessive allele for a disorder, they will develop the condition (no second X to mask it). Females have two X chromosomes (XX); they need two copies of the recessive allele to develop the disorder, making it far less likely.

Males have only one X chromosome (XY), so if this X carries the recessive allele for a sex-linked disorder, there is no second X chromosome to provide a dominant normal allele to mask it. Females have two X chromosomes (XX), so they need two copies of the recessive allele to develop the disorder, which is statistically much less common.
