How do you have a colorblind son if neither parent is colorblind?

It is just the DNA lottery. If neither parent is colorblind that just means that one of them (or both of them) have recessive genes for colorblindness that happened to show up in this particular child.

How is colorblindness transferred from the parent to the child?
We know that if a father is colorblind and the mother is neither colorblind nor a carrier, then the sons will not be colorblind. So, using logic, that means that the father can't cause a son to become colorblind. Process of elimination would point towards whenever a son is colorblind that it comes from the mother. A diagram explaining how colorblindness is inherited can be viewed in the related links.

A colorblind man and woman with normal vision whose father was colorblind have a son what is the probability that their son is colorblind?
Make a punnet square with the mother above, her genotype would be: X^B X^b, and the father to the left whose genotype is X^b Y.The probability of having a colorblind CHILD is 50%. The probability of them having a SON is 50%. Since we are asked what the probability of their SON being colorblind, it is 50% as well. The reason is because the chance of having a colorblind son, among sons only, (according to the punnet square) is 50%.
Why is a son who receives the allele for combinations from his mother always colorblind?
Since the mother would be considered a carrier, the gene will be produced in the offspring. the son will receive that gene and will be colorblind.
If a normal woman whose father is color-blind marries a colorblind man what are their chances of having a colorblind son?

What must occur for a girl to be colorblind?
Each parent must have the recessive allele for colorblindness.
What must occur for a girl to be color blind?
The girl must have a copy of the gene on each X chromosome. This means that she must have a father who is colorblind and a mother who is either a carrier or is colorblind.
Can two persons with normal vision produce a colorblind son?
No they will produce a child who is colour blind.
A womens father is colorblind She marries a colorblind man Will there son or daughter be colorblind?
Colorblindness is an X-linked recessive disorder. This means girls (who have the sex chromosomes XX) must have a colorblind X from dad and a colorblind X from mom. Boys only need to have one colorblind X to be colorblind because they have sex chromosomes XY (and have only 1 X). If the dad has it, he has the colorblind X. If the daughter has it, she must have gotten her mom's colorblind X. If the mom is colorblind, then every child they have will be colorblind. If the mom is not colorblind, then she must be a carrier - she must have 1 normal X and 1 colorblind X. Mom is either colorblind (with 2 colorblind Xs) or she is a carrier. Dad is definitely colorblind.
