Just when the Novel Prize looms clearly on the horizon, tragedy strikes: the reaction ceases to work well. The only difference between when the reaction was working and now is that the DNA polymerase is from a different source (isolated from a different organism). [NOTE: enzymes like polymerases used in most laboratories are purchased in kits from companies.] The Km of the "old" polymerase was 20 µM nucleotide, and the Km of the "new" polymerase is 100 µM. What is the first thing you would do to change the reaction conditions (using the new polymerase) in your attempt to get the reaction to work?
what are the options
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.
