Color Blindness is x-linked recessive. Therefore, it could not be heterozygous; the daughter would not be colorblind, but rather have normal vision.

what type of mutation is caused by red green color blindness?
(Apex Learning) She has at least one recessive color blindness allele.
A male with red-green color blindness has the genotype X^cY, where X^c represents the X chromosome carrying the recessive allele for color blindness. He inherited the recessive allele from his mother, who must have at least one X chromosome with the color blindness allele (either X^cX or X^cY). Since males inherit their X chromosome from their mothers and their Y chromosome from their fathers, the mother's genotype determines whether the son will express the condition.
Plato Users: A and B.
If the couple has a color-blind son, it would indicate that color blindness is caused by an X-linked recessive allele. This is because sons inherit their single X chromosome from their mother, who carries the recessive allele for color blindness but does not express it due to her second X chromosome providing the normal color vision gene.

Color blindness is a sex-linked trait that is carried on the X chromosome. Since males inherit their single X chromosome from their mother, if the mother carries the allele for color blindness, her son will inherit it and be colorblind. Females need two copies of the allele to be colorblind, so they can be carriers without exhibiting the trait.
