Which is a similarity between humoral and cell-mediated immune responses?

both are controlled by the phagocytes.

both are characterized by the production of antibodies.

both are branches of acquired immunity.

"Both are branches of acquired immunity" is the one among the following choices given in the question that is a similarity between humoral and cell-mediated immune responses. The correct option among all the options that are given in the question is the third option or the last option. I hope the answer helps you.

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.
