Humans with hypohidrotic ectodermal dysplasia have defects in the formation and function of their sweat glands. Males with the condition have reduced ability to sweat over their entire body. Females with the condition lose the ability to sweat only in patches of skin. Where must the gene that encodes this trait be located?

Question

Quizplus · Accepted Answer

Since males have reduced ability to sweat over their entire body, this trait is likely linked to the X chromosome. Females with the condition have a different phenotype, so it is not limited to a sex-linked trait. Therefore, the gene that encodes this trait is most likely located on the X chromosome.
