    The Hardy -Wemberg principle cannot operate If

    A)  the population is very large

    B)  frequent mutations occur in the population

    C)  the population has no chance of interaction with other populations

    D)  free interbreeding occurs among all members of the population

    Correct Answer: B

    Solution :

    : The Hardy-Weinberg principle says that allele frequencies in a population are stable and constant from generation to generation as lone as - the population is large enough and changes in allele frequencies due to chance or accident are insignificant. - mating occurs at random. - mutation does not occur or if it does occur it must reach a state of equilibrium. - all the members of the population survive and have equal reproductive rates. Hardy and Weinberg, through this law, have been able to explain why a population as a whole with all its variations and genotype frequencies continue to remain unchanged for many generations.
