Question

If a woman's father is color blind, what is the probability that her son will be color blind? What is the probability that her son's daughter will be colorblind? Color blindness is an X-linked inheritance.

Answer 1

If a woman's father is color blind, there is a 50% chance that her son will be color blind. For her son's daughter, there is a 50% chance that she will be a carrier of the color blindness trait.

Step-by-step explanation:

X-linked recessive inheritance is much more common because females can be carriers of the disease yet still have a normal phenotype. If a woman's father is color blind, there is a 50% chance that her son will be color blind. For her son's daughter, there is a 50% chance that she will be a carrier of the color blindness trait.

For color blindness, if a woman's father is color blind, there is a 50% chance that her son will be color blind. This is because the mother passes the recessive allele for color blindness to her sons. As for her son's daughter, there is a 50% chance that she will be a carrier of the color blindness trait.
