Detailed explanation-1: -Since males only have on X chromosome, if it is present, it will be expressed. So if a female is color blind, her genotype would be XbXb, and a man with normal vision would have the genotype XBY. There would be a 100% chance of male offspring being colorblind.
Detailed explanation-2: -Each daughter has a 50% chance of being a carrier and each son has a 50% chance of being color blind. The daughters who are carriers can have color blind sons with the same logic.
Detailed explanation-3: -Hence, probability of an affected daughter is one out of two or 1/2 or 0.50.
Detailed explanation-4: -Final answer: A marriage between a colourblind man and a normal woman produces all carrier daughters and normal sons.
Detailed explanation-5: -Answer and Explanation: There is zero probability that the female offspring between a male with normal vision (XEY X E Y )and a colorblind female (XeXe X e X e ) will be colorblind.
