A scientist designs an experiment to determine the effects of pocket gopher herbivory on soybean crops. The scientist designs a treatment consisting of 200 soybean plants grown inside a cage in an agricultural field. A pocket gopher is introduced into the cage for three days. Which of the following designs would provide the best control for this treatment? a. 200 soybean plants grown inside another cage in the same agricultural field without a pocket gopher introduced.
b. 200 soybean plants grown in the same agricultural field.
c. 200 soybean plants grown inside a cage in a greenhouse without a pocket gopher introduced.
d. 200 corn plants grown in the same agricultural field.

It would be the equator.

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.
