If a colourblind woman marries a normal visioned man, their sons will ...
First, we need to understand the genetics of colorblindness. Colorblindness is a sex-linked recessive trait, meaning it is carried on the X chromosome. Men have one X and one Y chromosome, while women have two X chromosomes.
Explanation:
- Colorblind woman: A colorblind woman carries the colorblind gene on one of her X chromosomes.
- Normal visioned man: A normal visioned man does not carry the colorblind gene on his Y chromosome.
- Sons: Sons inherit their X chromosome from their mother and their Y chromosome from their father.
Answer: All sons of a colorblind woman and a normal visioned man will be colorblind. This is because the sons will inherit the colorblind gene from their mother's X chromosome and will not have a second X chromosome to override the colorblindness gene. Therefore, all their sons will be colorblind.
