Males that are X+Y have normal color vision, while XcY males are colorblind. Punnett Squares. To determine the inheritance of red-green colorblindness (or any other X-linked trait), the genotypes of the parents must be considered. read more

If one X chromosome of a female had the mutations and the other did not, she would not be color blind. However, color blindness outside of Punnett squares is not this simple. Not all color blindness is due to an X-linked genetic mutation. read more

Punnett squares are really just a way to organize all the genes and to figure out how likely a combination of genes is. For your current situation, if we assume that you do not carry a colorblindness gene, then we would say you are XX. read more

first of all you have to consider that color blindness can be an x-linked mutation, thus if the kid might not be color blind because the mother is not. The other things we don't know if the genes are homozygous or heterozygous. read more
