Answer 1

The correct option is D All of the above

Morgan worked with the tiny fruit flies, Drosophila melanogaster. He found Drosophila suitable because -

• They could be grown on simple synthetic medium in the laboratory.
• They complete their life cycle in about two weeks, and a single mating could produce a large number of progeny flies.
• There was a clear differentiation of the sexes, the male and female flies are easily distinguishable.

So, the correct option is 'It has a short life span'.
