Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
T H MORGAN EXPERIMENTALLY VERIFIED CHROMOSOMAL THEORY OF INHERITANCE BY USING Drosophila melanogaster BECAUSE
A
IT COMPLETES ITS LIFE CYCLE IN ABOUT TWO WEEKS
B
IT PRODUCES LARGE NUMBER OF PROGENIES IN SINGLE MATING
C
MALE IS DISTINCT FROM FEMALE
D
ALL OF THE ABOVE
Explanation: 

Detailed explanation-1: -Solution : Morgan selected fruit flies for his genetical experiments for the following reasons :<br> (a) They could be grown on simple synthetic medium in the laboratory. <br> (b) They complete their life cycle in about two weeks and a single mating could produce a large number of progeny flies.

Detailed explanation-2: -Final answer: 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 life cycle in about two weeks.

Detailed explanation-3: -Thomas Hunt Morgan, who studied fruit flies, provided the first strong confirmation of the chromosome theory. Morgan discovered a mutation that affected fly eye color. He observed that the mutation was inherited differently by male and female flies.
