Biology - Principles of Inheritance and Variation Question with Solution | TestHub
Morgan choseDrosophila melanogasterfor his experiment because of the following characteristics EXCEPT __________
Options:
Answer:
Solution:
T.H. Morgan selectedDrosophila melanogaster(fruit fly) for his genetic experiments for several reasons:
They could be grown on simple synthetic medium in the laboratory.
They complete their life cycle in about two weeks (short life span).
A single mating could produce a large number of progeny flies (high rate of reproduction).
There was a clear differentiation of the sexes, and it has many types of hereditary variations that can be seen with low power microscopes.
Drosophilahas pairs of chromosomes and exhibits linkage. In fact, Morgan extensively studied linked genes and recombination inDrosophila. Therefore, the statement that it lacks linked characters is incorrect.
Answer: it lacks linked characters.
