Do we expect a son/daughter to have a trait if the trait is inherited in the following way (for each, please answer Y/N/P/W for yes, no, possibly, or ‘what!? – that doesn’t make sense!!’). Please fill out the grid for each type of inheritance. For example, a X-linked dominant female-limited trait would look like this:

The answer would be c

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
