2. 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
