A researcher studying llama genetics would like to clone her gene of interest into the pUC19 cloning vector using the blue-white screening approach we discussed in class. Below are the vector and llama DNA fragment to be cloned into the vector. The restriction enzyme sites indicated on both DNA molecules. Which restriction enzyme should she use in order to get the largest possible DNA fragment cloned into the vector

The moths will eventually become extinct

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.
