Question

Can a colorblind mother have a normal son?

Answer 1

Colorblindness:

1. Colorblindness is an X-linked recessive genetic disorder.
2. No, a colorblind mother can’t have a normal son.
3. Colorblind means she is homozygous for the defective genes and the genes are present on both the X-chromosomes.
4. So, the son will get an X chromosome from his mother so he will be colorblind.
5. Chances of having color blindness are more in males compared to females as they carry only one X chromosome.
6. So, a colorblind mother can't have a normal son.
