Each clan will be isolating two different bacteria, Pseudomonas sp. and Bacillus sp., from the same soil sample. What two traits provide the basis of your Pseudomonas sp. enrichment strategy

The former bacteria, Pseudomonas sp., has the ability to utilize benzoate as a source of carbon. Pseudomonas sp. can also migrate in the direction of areas with higher oxygen concentrations.

Whereas the latter, Bacillus sp., does not possess these characteristics.

Explanation:

The two traits mentioned above will provide the basis upon which the strategy for enrichment can be made.

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.
