Umm.. sometimes?
Hemophilia is considered a sex-linked disorder. Why?
It only affects one sex.
It is recessive and carried on a sex chromosome: X.
It is recessive and carried on a sex chromosome: Y.
It impacts the sex of the baby that you'll have.
Why do sex-linked disorders carried on the X chromosome impact males more than females?
Because males only get one X and if it's affected, they automatically get the disorder.
Because males have a weaker immune system.
Because males have 2 X chromosomes.
Because males are more likely to get bad X chromosomes from their Dad.
