"Sex Limited Inheritance in Drosophila" (1910), by Thomas Hunt Morgan
In 1910, Thomas Hunt Morgan performed an experiment at Columbia University, in New York City, New York, that helped identify the role chromosomes play in heredity. That year, Morgan was breeding Drosophila, or fruit flies. After observing thousands of fruit fly offspring with red eyes, he obtained one that had white eyes. Morgan began breeding the white-eyed mutant fly and found that in one ...

Why do scientists study fruit flies?
Compare this with experiments on a few dozen chickens or mice… The fruit fly allowed geneticists to conduct experiments with an unprecedented statistical power. Today thousands of scientists around the world use Drosophila as a model organism for the same reasons Morgan used this pesky insect in his research over a century ago:
Model organisms: the fruit fly
The fruit fly (Drosophila melanogaster, or 'Drosophila') is the most used and one of the most well understood model organisms. ...
