Question
Hemophilia is a bleeding disorder that primarily affects males. Which of the following statements best explains why females are less likely to express the trait.(1 point)
Responses
When paired with a normal X, the affected x allele is masked (Xx), suppressing the trait. Since females have only X alleles, the probability increases.
When paired with a normal X, the affected x allele is masked (Xx), suppressing the trait. Since females have only X alleles, the probability increases.
Females have an XY chromosome pair, so the trait is frequently expressed
Females have an XY chromosome pair, so the trait is frequently expressed
Males without an affected x allele always express the trait (XY)
Males without an affected x allele always express the trait (XY)
When paired with a normal X, the affected x allele is masked (Xx), suppressing the trait. Since females have only X alleles, the probability decreases.

The correct response is:
**When paired with a normal X, the affected x allele is masked (Xx), suppressing the trait. Since females have only X alleles, the probability decreases.**
This statement accurately explains that females have two X chromosomes, so if one X chromosome carries the normal allele, it can mask the effect of the affected allele. In contrast, males have only one X chromosome, so if they inherit the affected allele, they will express the trait.
