9. Snail species A has a shell that spirals counterclockwise, but a mutation has caused some individuals to have a clockwise shell. The genitalia of the two versions are incompatible, leading some scientists to say that the clockwise snails are reproductively isolated. Could the clockwise snails become a new species?

Then it is june the conclusion to the second sentence is just restating "if it is june then it is summer"

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.
