The chart above shows how a star's temperature relates to its color. rigel is a blue star, betelgeuse is a red star, and the sun is a yellow star. how do the temperatures of these stars compare? a. the three stars have different colors but the same temperature. b. betelgeuse is hotter than the sun and cooler than rigel. c. rigel is hotter than betelgeuse and cooler than the sun. d. the sun is hotter than betelgeuse and cooler than rigel.

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.
