In a woman who is a carrier of a mutant OTC deficiency allele, her sons who receive the mutant allele will be affected and her daughters will be carriers who may or may not be symptomatic, depending on random X inactivation in the liver. 1) Is this a single gene inheritance or multifactorial disease? 2) Is there a strong genetic or environmental cause to the development of this disease? If both genetic and environmental causes are implicated, you have to indicate each of them separately.
5. In humans, one type of color-blindness, an inability to distinguish between red and green, is inherited as a sex-linked character on the X chromosome. It is recessive. a) If a color-blind man marries a homozygous normal woman, what chance is there for the children to be color-blind? b) A normal man marries a color-blind woman. Which, if any, of their children are likely to be colorblind? c) Why is it so commonly believed that women cannot be color-blind?
Consider a couple: a woman who is homozygous for a recessive mutation that causes X-linked colorblindness, and a man with full color vision (he does not carry a copy of the mutation). a) What is the probability that a son of this couple will be colorblind? b) What is the probability that a daughter of the couple will be colorblind?
