Question

Red-green color blindness is caused by an X-linked recessive gene. In a family, the mother is a carrier of this gene while the father does not have the gene. What are the possible effects on their children? Half of the daughters are normal and half of the daughters are color-blind. Half of the boys are normal and half of the boys are color-blind. Half of the boys are color-blind and half of the girls are color-blind.

Answer 1

The possible effects on their children may be a 50-50 percent chance of getting colorblind. It's not a full 100% because some children may not inheritage the colorblindness from their carrier mother.
