20 Points - BIOLOGY Which of the following best describes an example of how genetic codes of organisms have been used to help hierarchically classify living things?

The common nucleic acid sequences of polar bears and black bears can be deduced from their classification in the same genus, Ursus.
Viruses contain DNA which is used to classify which hosts they will infect into a Linnaean taxonomy of viruses.
Since kangaroos and opossums both have developed pouches to carry their young, it proves that they share DNA sequences and belong to the same species.
Even though Eubacteria and Archaebacteria look similar, differences in their ribosomal RNA led to their classification into different domains.

I’m not exactly sure what your trying to ask, but if it’s how an organelle is similar to a body system or a part a nucleus is like a in function. but i don’t fully understand what you’re trying to ask

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.
