Fruit flies are one of the best materials for genetic studies because of all, except
Ability to grow on simple synthetic medium in the laboratory
Short life span
Production of a large number of progeny in each mating
Presence of few externally visible and identifiable contrasting traits
In $1900$ $A.D.$ three biologists independently discovered Mendel's principles. They are
.............. noted that behavior of chromosomes was parallel to the behavior of genes and used chromosome movement to explain Mendel's laws.
Mendel's results on the inheritance of characters were rediscovered by
Discuss why Drosophila has been used extensively for genetical studies.
