Assertion :- Drosophila were found very suitable for genetical studies.
Reason :- They complete their lifr cycle in about two weeks and produces fix number of offsprings.

Drosophila complete their life cycle in about..........weeks

Drosophila complete their life cycle in about..........weeks

Drosophila melanogaster is found to be very suitable for genetic studies because (i) They could be grown in simple synthetic medium in the laboratory (ii) They complete their life-cycle in about 14 days (iii) A single mating could produce a large number of progents (iv) Male and females are clearly distinguishable (v) It has few hereditary variations that can be seen with high power microscopes Select how many are correct statements.

Assertion: The offsprings produced by asexual reproduction are genetically identical. Reason: They are produced by mitotic or amitotic cell division.
