The probability that their son exhibits the 'color blind' trait is 0%. It is a type of inheritance linked to the X chromosome.

<h3>Inheritance linked to the X chromosome</h3>

In men, the patterns of inheritance linked to the X chromosome don't follow conventional mendelian inheritance because men have only one X chromosome.

Conversely, women have two X chromosomes, thereby the inheritance pattern resembles Mendelian inheritance.

It is important to highlight that color blindness is a recessive trait on the X chromosome.

In this case, the mother is a carrier, thereby the probability of passing this trait as a carrier to her son is 50%, whereas the father is normal, thereby the probability of passing this trait to his son is 0%.
