Green-weakness partial color blindness, or deuteranomaly, is a sex-linked recessive trait. The green-weakness allele, g, is recessive to the allele for normal color vision, G. Another form of abnormal vision is total color blindness which is due to an autosomal gene, t, which is recessive to its counterpart allele, T, for normal vision. A man with a normal phenotype marries a woman with green-weakness partial color blindness. Both individuals are heterozygous for autosomal color blindness. What phenotypes and phenotypic frequencies...

Red-green color blindness is due to an X-linked recessive allele in humans. A widow's peak (a hairline that comes to a peak in the middle of the forehead) is due to an autosomal dominant allele. Consider the following family history: A man with a widow's peak and normal color vision marries a color-blind woman with a straight hairline. The man's father had a straight hairline, as did both of the woman's parents. Use the family history to make predictions about...
