WILL GIVE BRAINLIST NEED HELP ASAP A rain forest found in Brazil has a larger variety of organisms in 10 square miles than the same area in taiga in Canada. What can be said about the rain forest?

Question 4 options:

it does not have any keystone species

it has very few abiotic factors

it has more biodiversity

it is a healthier ecosystem

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. 

Sorry  i don't understand can you rephrase that
