XnY one color blind boy. 1  Probability of having a color blind daughter is (1/2 x 1/2) or 1/4 or 25% (0.25) This is because both sex and colorblindness are involved in the solution.  The probability that their first son is color blind is 50% (0.50). In this question only males are part of the solution.
Now if your daughters married men who weren't colorblind, their Punnett square would look like this: As you can see, there would be a 1 in 4 or 25% chance for a daughter who is a carrier (X c X), a 25% chance for a colorblind son (X c Y), and a 50% chance for a child without the colorblind gene (XX, XY).t is different for a son who can only get the gene that causes colorblindness from his mother and only needs one copy to be colorblind. These two different situations arise from the fact that the gene that causes colorblindness is found on the X chromosome and is recessive.
