A graph titled Average hamster weight (kg) vs. Amount of drug(mg/day)^ prime prime shows a downward -sloping line that reaches a minimum value and then stays there over the remainder of the graph Average hamster weight kg) vs. Amount of drug (mg / day ) Average hamster weight ( kg ) 10 Amount of drug (mg /day ) What noticeable trend from this graph might be used to make a conclusion ?

That would be a working theory.

It is evolution, because we all have some of the same traits like eye color or shape or ears.

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.
