In the three panels below, simulations were performed in which it was assumed that the were subject to only genetic drift (i selection). Populations populations with were scored for the frequency of over time; populations a frequency of 50%. Each line represents a different replicate of the conditions and the three panels differ only in the size of the population they represent. Rank the populations in order from smallest to largest:

Solution

The answer must be C, A and B . The population of allele which is lowest in the large group of population will have less deviation in frequency and maximum it will be constant. So from the figures you can conclude that C is relatively constant as it has constant frequency . Next compared to B and A , A has less deviations compared to B . so A must be next higher to C . The highest deviation is in B, so it has more deviations,. Hence option D.
