Females cannot inherit red-green color blindness. Her mother is a carrier, and her father does not have the condition.

Answer 1

The correct answer is - Her mother is a carrier, and her father has the condition.

Step-by-step explanation:

Colorblindness is a sex linked recessive disease that is passed from the parent to the offspring through X chromosome that have recessive gene of the disease. It is rare in the females as the very low chances of the females to inherit two copies of disease gene allele. But as only one allele is present in males of X chromosome and if there is disease copy he will be color blind.

To get a colorblind female the girl child must get two copies of these allele that has recessive X chromosome one from her carrier mother and other from her conditioned father. Check image for punnet.

Thus, the correct answer is - Her mother is a carrier, and her father has the condition.
