Why is it necessary for the genetic material in a cell to exist in chromatin form during normal cellular activity, and not in chromosome form? a)it requires more surface area in the cell to have the cells condense. b)condensing into chromosome form requires more energy than the cell has to exert. c) chromatin prevents genetic material from being broken off during replication. d)chromatin form allows the genetic code to be read and proteins to be made.

D- During interphase, when the cell is not dividing, chromatin is less tightly packed compared to our chromosomes, which allows transcription to occur. 

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.
