Identifying Drosophila mutants Why are flies good models for genetics? small, lots maintained in small area cheap large volume of literature (lots known about them) 4 chromosomes = simple genetics phenotypes easy to observe many offspring from one mating (500+ eggs) short generation time Life cycle of Drosophila
