What are the 3 Hardy Weinberg rules?

Question

I'm not talking about the 5 things that would have to be in order for a population to be in equilibrium like: random mating, large population, no mutations, no migrations, and no natural selection. I'm talking about 3 rules.Thank you for your help.

Answer 1

Do you mean how to do the calculation?

For a locus with 2 alleles:
p+q = 1
p^2 + 2pq + q^2 = 1
p, q are allele frequencies of alleles A, B, respectively
p^2, 2pq, q^2 are genotype frequencies of AA, AB/2, and BB

For a locus with 3 alleles:
p+q+r = 1
(p+q+r)^2 = 1

When the 5 things you listed are all satisfied, you know the population is in Hardy-Weinberg equilibrium. And then you can use the above method to calculate for the next generation's allele & genotype frequencies.

On the other hand, if one of the 5 is acting (e.g. there is natural selection), then [p+q = 1] and/or [p^2 + 2pq + q^2 = 1] will not be true, depending on where the selection happens.

Answer 2

I'm always up for a little random mating with a natural selected migrating population with no mutations....

Answer 3

a single locus with 2 allelas A and a etc etc etc.
Generalization for more then two allelas
Generalization for polyploidy
Complete Generalization
I am not too sure what you mean?
