If a plant’s leaves developed so that it’s vascular tissue only contained xylem how would this affect the rest of the plant’s physiological processes?

A) The carbon dioxide required for photosynthesis would not be absorbed and transported to leaf cells and photosynthesis would stop

B) glucose produced during photosynthesis in the leaf cells wouldn’t reach the rest of the plant and the cellular respiration in the plant’s other cells wouldn’t function

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
