During normal climatic conditions with regular rainfall, the average beak depth for a population of finches was 6.8mm. researchers found that after a drought, average beak depth increased to 8.8mm. birds with deep beaks (> 9mm) were better able to eat large, hard seeds. small hard seeds were also available after the drought, but could only be eaten by birds with shallow beaks (< 7mm). choose the graphical representation and term that best represents what would happen in the post-drought finch population if both types of seeds continue to be available.

Cell division is important to single celled organisms because it allows the cells to reproduce. through cell division, cells make exact copies of themselves. when single celled organisms go through cell division, they make exact copies of themselves which is how they reproduce.

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.
