The Hardy – Weinberg principle has
seven conditions that should occur in the evolution of the population. One is
when mutation does not happen. Two, is when natural selection is not occurring.
Three, if the population is infinitely large. Four, if all the members of the
population produce offspring. Five,
sexual intercourse is random. Six, the population will produce the same number
of offspring. And lastly, the population does not migrate from one place into
the other. Th thing that would disrupt the genetic equilibrium is the mutation.
