Apopulation of scarab beetles has an annual per capita birth rate of 0.8 and an annual per capita death rate of 0.5. estimate the number of individuals added to or lost from a population of 1,000 individuals in one year. choose the correct answer from the following choices, and then select the submit answer button. 3,000 individuals added 50 individuals lost 300 individuals added 30 individuals added 500 individuals lost

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.
