Question

Quizplus · Accepted Answer

Red-green color weakness is inherited through a recessive gene carried on the X chromosome. Since males only have one X chromosome inherited from their mother, if their mother carries the gene for color weakness on one of her X chromosomes, there is a 50% chance that her son will inherit the gene and also have the color weakness.
