A yard is mostly grass with no herbivores. On May 1, you measure that the average above-ground biomass density in 20 plots is 10 grams Carbon per meter squared. You wait until May 15 and you do NOT mow the lawn. On May 15, you study the 20 plots and find that there has been net primary productivity equal to about 15 grams Carbon per meter squared. You know that the NPP is less than the GPP, due to respiration. In your plots, organisms performed cellular respiration that accounts for the difference between NPP and GPP. Which organisms performed this cellular respiration

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. 

Yes yes yes very good
