Compared to absolute dating, what is an advantage of relative dating? a.) fossils must be in undisturbed rock layers to determine age. b.) age, in years, cannot be determined for an individual fossil. c.) age can be determined by comparing the depth of one rock layer to another. d.) two or more fossils must be compared to determine age.

There is no limit, saying to the age range of the fossils being dated. relative dating is used to determine how old or young the fossil is compared to other artifacts or items.

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. 

Non living: objects like rocks, buildings, and snow.living: animals, plants and humans.
