Question

A normal vision femal whose father is colour-blind marries a normal vision male. what would be the probability of her sons and daughters to be colour blind?

Answer 1

heya there!!


the woman is not color-blind, but her father was. This means she is a carrier of the gene. She marries a man that is not color blind, and thus doesn’t carry the gene at all. If they have children:

If they have a son, the chance to be colourblind is 50%

If they have a daughter, the chance to be a carrier is 50%
