If a rat had a lesioned (surgically removed) amygdala and was then placed in the same room with a cat, the rat would likely appear tame, neutral, perhaps even playful. The amygdala is a structure located in the temporal lobe that participates in the control of emotional and motivated behaviors. In the rat it is considered that two of the subdivisions of the amygdala, the medial amygdala (Am) and the posteromedial nucleus, belong to the vomeronasal system,

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.
