The fruit fly Drosophila melanogaster was found to be very suitable for experimental verification of the chromosomal theory of inheritance by Morgan and his colleagues because:
| 1. | a single mating produces two young flies |
| 2. | smaller female is easily recognisable from a large male |
| 3. | it completes its life cycle in about two weeks |
| 4. | it reproduces parthenogenetically |
