NEETZoologyPrinciples of Inheritance and Variation
Why were fruit flies found suitable for genetic studies?
Options
- AThey were easy to find in nature
- BThey required complex media to grow
- CThey completed their life cycle in about two weeks
- DThey had few hereditary variations
Correct answer
C. They completed their life cycle in about two weeks
Step-by-step solution
Following this synthesis of ideas, experimental verification of the chromosomal theory of inheritance by Thomas Hunt Morgan and his colleagues, led to discovering the basis for the variation that sexual reproduction produced. Morgan worked with the tiny fruit flies, Drosophila melanogaster (Figure 4.10), which were found very suitable for such studies. They could be grown on a simple synthetic medium in the laboratory. They complete their life cycle in about two weeks, and a single mating could produce a large numb
