Question

If color blindness is an X-linked recessive trait, what genotype in a father and a mother would be predicted to produce a 1:1 ratio of normal to color-blind offspring?

Answer 1

The genotype would be X'Y for the father (he would be colorblind)
The genotype would be X'X for the mother (she would be a carrier)
The offspring would be X'X' _ X'X_ X'Y_ XY
The ratio would be 1:1 normal to colorblind
Hope this was helpful(;
