The tendency of the population to remain in genetic equilibrium may be disturbed by:

The loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population is called as:

At a particular locus, the 'A' allele frequency is 0.6 and that of 'a' allele is 0.4. What would be the frequency of heterozygotes in a random mating population at equilibrium? 

In some African populations, the frequency of the sickle cell allele in the human population is much higher than normal. This can be an example of:

A population will not exist in Hardy-Weinberg equilibrium if:
