Title: Biology Question: the Hardy-Weinberg principle? Post by: zzz1090 on Apr 11, 2012 True or False:
According to the Hardy-Weinberg principle, the frequency of alleles in a population tends to change even when nothing specifically affects them. Title: Biology Question: the Hardy-Weinberg principle? Post by: smile on Apr 11, 2012 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.
Title: Biology Question: the Hardy-Weinberg principle? Post by: rivertube on Apr 11, 2012 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. |
