Background information: On average, an adult male sea otter weighs 36 kg (79 pounds), with some individuals weighing as much as 45 kg (99 pounds). A female weighs an average 23 kg (50 pounds). To
maintain their weight, otters much consume 250 kilocalories for every 1 kg of body weight each day to
survive. Otters eat almost entirely small invertebrates for which they must dive to catch.
You have been tracking an adult female otter who weighs 25 kg. Answer the following questions based on
the data provided.

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.
