The roles of scientists and engineers in the advancement of science and technology complement each other. in general, scientists conduct in-
depth scientific study and research, which provides the foundation for technology, while engineers use this knowledge to carry out the practical
application of science and technology to solve problems. when scientists and engineers test new ideas, they follow similar procedures. match
these steps, which are only a small part of the testing process, to either scientific inquiry or engineering design.

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.
