The chance of producing a son with normal vision if the father is color blind, and the mother is homozygous for the normal trait is 100%.
Color blindness is a genetic disorder associated with the X chromosome. A baby son cannot get the X chromosome from his father because his father has passed only the Y chromosome to combine with the X chromosome from his mother. This means that when the X chromosome from the mother and Y chromosome from the father were combined, a baby boy was formed.
This further means that if the father is colorblind, his Y chromosome cannot have the color-blind genes as it is only present on the X chromosome. And the mother is homozygous (XX) for the normal trait, the son would be heterozygous (XY) for normal vision.
Therefore, the chances of a son with normal vision are 100%.
