Biology Question: the Hardy-Weinberg principle?

uh no, its the other way around. it says that allele frequency tends to not change without disturbances. that doesn't mean that the hardy-weinberg principle really applies to anything natural though, because in nature there are always influential factors.

I do not specificaly understand your question, but i will try to understand it as best i can.

The Hardy-Weinberg principle is the principle of genetic equalibrium and states five conditions that must be met in order for a population to be in genetic equalibrium in which nothing changes. those conditions are:

1. Large population
2. no mutations
3. random mating
4. no natural selection
5. isolated population

Unless these conditions are met, then a population is constantly changing. So if the frequency of alleles are changeing in a population, then one or more of the above five conditions are not met. I would have to say false to your question on the basis that i don't believe anything in the Hardy-Weinberg principle states anything about frequency of alleles changing when nothing affects them.
