Solution
The correct option is D Fruitfly
Fruitfly has a relatively short generation time of about two weeks. It easily survives and breeds well in the lab. Their body size is ideal; big enough to see them without microscope as well as small enough to maintain large number of cultures. It has very large chromosomes in some of its cells, which are useful tools for chromosomal studies. Many aspects of its phenotype are genetically controlled; for example, the external results of mutations in genes that govern eye color, bristle number are easily visible. Correct answer is D.
