Question

can a female have an x - linked disorder?
a never
b yes, occurs frequently
c yes, occurs infrequently
d yes, always occurs

Explanation:

X - linked disorders are typically recessive. Females have two X chromosomes (\(XX\)). For a female to have an X - linked disorder, she needs to inherit the recessive allele from both parents. This is less common compared to males (who have \(XY\) and only need to inherit the recessive allele from the mother). So, it is possible but infrequent.

Answer:

C. Yes, occurs infrequently
