The Hardy-Weinburg equation describes a situation...

Post by Chemhalp » Sat Jan 24, 2009 5:15 pm

The Hardy-Weinburg equation describes a situation where there is no change in allele frequencies.

Describe four scenarios where Hardy-Weinberg no longer applies.

My exam is on monday and I have misplaced my lecture notes pertaining to this subject, I've search all over the net but can't find four scenarious where H-W no longer applies.

Any help Bio-online?

Well alleles refer to genes, so HW refers to a rare case where a certain population's gene pool does not change. Look at the assumptions for HW and think about how genes can be introduced and removed from a population.

I have had a think about it and I could only decide that H-W equilibrium wouldn't take place if the conditions for HW were incorrect

A small population size which would cause genetic drift right?

That covers two of the principals right? large pop size and no gene flow...

If the alleles in the population were undergoing mutation
If there was no random mating.
If there was natural selection.

Am I getting close? :)
