Q

Predicted genotypes in Hardy-Weinberg equilibrium using frequency of alleles

A

p^2 + 2pq + q^2 = 1
p: proportion of allele p
q: proportion of allele q

Q

What if Hardy-Weinberg conditions are not occurring?

A

Some evolutionary process is happening, and the predicted genotype frequencies of the resulting population are DIFFERENT from the parent population

Q

What if Hardy-Weinberg conditions are occurring?
