Red-green colorblindness is an X-linked recessive trait. Neither John nor Ann is colorblind, but Ann’s father is colorblind. What fraction of the daughters of John and Ann are expected to be carriers for the trait? Group of answer choices

Explanation:

Colour blindness is recessive sex-linked traits, carried by the X chromosome that is manifested as the difficulty of an individual to distinguish different colours properly.

From the question above Ann doesn't have color blindness but her father does, thus there is a possibility that Ann is an heterozygous carrier of color blindness.

Therefore the chances of having a carrier for color blindness in a daughter is 25% or 1/4

So, the answer is 25%
