In humans one of the genes determining color vision is located on the X chromosome. The
dominant form (C) produces a normal color vision; red-green deficiency (c) is recessive. If a man
with normal color vision marries a color-deficient woman, what are the probability of them having a
color-blind son? A colorblind daughter?
If the phenotype of a heterozygous is intermediate between the phenotypes of the two
homozygous, this pattern of inheritance is called
If the heterozygous expresses of both homozygous and
heterozygous(not intermediate, but showing both traits), this called
. In many genes, usually with similar effects, on a phenotype, control the inheritance of a trait.
