How did morgan determine that eye color in drosophila? Morgan began breeding the white-eyed mutant fly and found that in one generation of flies, the trait was only present in males. Through more breeding analysis, Morgan found that the genetic factor controlling eye color in the flies was on the same chromosome that determined sex.
What experiment did Thomas Morgan do? One day in 1910, American geneticist Thomas Hunt Morgan peered through a hand lens at a male fruit fly, and he noticed it didn’t look right. Instead of having the normally brilliant red eyes of wild-type Drosophila melanogaster, this fly had white eyes.
How did Morgan discover crossing over? Morgan’s first attempts to find tractable mutations to study were quite disappointing. Fortunately, he persevered and found the white-eyed fly1. This led to his discovery of sex-linked inheritance and soon with the discovery of a second sex-linked mutant, rudimentary, he discovered crossing over.
Why does Morgan use Drosophila? Thomas Hunt Morgan, an embryologist who had turned to research in heredity, in 1907 began to extensively breed the common fruit fly, Drosophila melanogaster. He hoped to discover large-scale mutations that would represent the emergence of new species.
