Question

Which allele combination represents a female who is a carrier for an X-linked recessive disorder?

XRX
XX
OXY

Answer 1

The allele combination that represents a female carrier for an X-linked recessive disorder is XRX.

Step-by-step explanation:

In the case of X-linked recessive disorders, the allele combination that represents a female carrier is XRX. This means that the female has one normal X chromosome (XR) and one X chromosome with the recessive allele (X). The normal X chromosome is enough to mask the effects of the recessive disorder, but the carrier female can pass on the recessive allele to her offspring.
