Discuss why Drosophila has been used extensively for genetical studies.
Morgan worked with the tiny fruit files,called Drosophila melanogaster,very suitable for such studies, as :
$(i)$ They could be grown on simple synthetic medium (ripe banana) in the laboratory.
$(ii$) They could be grown on simple synthetic medium (ripe banana) in the laboratory.
$(iii)$ They complete their life cycle in about two weeks.
$(iv)$ A single mating could produce a large number of progeny flies.
$(v)$ There was a clear differentiation of the sexes(sexual dimorphism) -the male and female flies are easily distinguishable.
$(vi)$ It has many types of hereditary, variations that can be seen with low power microscopes.
