Answer 1

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

Step-by-step explanation:

The allele combination that represents a female who is a carrier for an X-linked recessive disorder is X'X'. In this case, the X chromosome carries the recessive disorder allele, denoted by X', while the other X chromosome carries the normal allele. As a carrier, the female does not have the disorder herself but can pass it down to her offspring.
