The eastern coral snake and Texas coral snake look almost identical and are often mistaken, but they are actually different species. Because they are different species, what can be concluded?

a They will have sterile offspring.
b They have different venom.
c They have different coloring patterns.
d They cannot hunt prey in the same manner.

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. 

The category is the thing that is most simmilar throughout a period

Yes yes yes very good
