Information about the four organisms can be found on the internet. Use credible websites to find answers to the question you developed in part A. Based on this data, draw your own dichotomous key. Questions I developed in part A:

Is it a unicellular organism?

Is it found inside the human body?

Is it visible without a microscope?

Can it produce its own food?

Can it be used in making food?

Ithink the answer is c. i’m not sure though i’ll notify you when i have an exact answer!

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. 

Okay cool  so what is the question?
