small isolated population

B

large isolated population

C

non-reproductive population

D

slow reproductive population

  • In a long term experiment of a population of Drosophila melnogaster, the frequency of two alleles 'a' and 'b' of a multi-allelic locus X over time has been shown in the following graph. 6 students were asked to evaluate the observed pattern and their inferences are given below. Statement 1: Enviorment is not uniformly slective. Statement 2: Population may be under artificial selection. Statement 3: Genetic variability is progressively reduced. Statement 4: Genetic varuability is progressively increased. Statement 5: Mechanism such as genetic drift is operating from time to time. Statement 6: Selection is favouring a particualr genotype through directional selection. The appropriate conclusions were draws by
