Question

Fruitfly Drosophila melanogaster was found to be very suitable for experimental verification of chromosome theory of inheritance by Morgan and his colleagues because.

• A. It reproduces parthenogenetically
• B. Smaller female is easily distinguishable from large male
• C. A single mating produces two young flies
• D. It completes life cycle in about two weeks

Answer 1

The correct option is D It completes life cycle in about two weeks

The fruit fly, Drosophila melanogaster was found to be very suitable for experimental verification of chromosomal theory of inheritance by Morgan and his colleagues because it completes its life cycle in a very short period (ie, about two weeks). a single mating produces many offsprings. larger female is easily recognisable from smaller male.

So, the correct answer is 'It completes life cycle in about two weeks'.
