PLEASE HELP 15 POINTS A biochemist is studying several different species of bacteria to determine if they have a common evolutionary ancestor. Which of the following would provide the best evidence that the species are closely related?

Comparing the different hosts each species of bacteria uses
Comparing the metabolic pathways of each species of bacteria
Determining the conditions under which each species of bacteria will survive
Determining the type of disease each species of bacteria may cause

Life, yes life it self madden

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.
