Find the difference between the recessive allele frequencies from
generation one to generation two. (Answer as a number between 0 and 1
rounded to 2 decimals) (2 marks) *
In one generation of Arctic char, 473 out of 589 males had the intense red color during
breeding season, which is the dominant trait. In the next generation, 504 out of 570 had
the dominant trait.
Your answer

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.
