Describe the hypothesized sequence of chemical and biological events that preceded the origin of eukaryotic cells

Paleontologists study the origins of life on Earth by studying the fossil records. Paleontologists work with other scientists to identify fossils of microscopic organisms, plants, invertebrates, and vertebrates at archaeological sites.

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.
