In this chapter, you will learn about the processes involved in transforming light energy into the potential energy in ATP and NADPH molecules, which are then used as sources of energy for building food molecules (carbohydrates). Before beginning this chapter, you should be able to describe the energetic differences between catabolic and anabolic pathways in metabolism

4, two dominant and two recessive

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.
