Hardy Weinberg equilibrium states that the frequency of allele will remain the same in the absence of disturbances such mutation,no gene flow, no selection, random mating and infinite population size
the equilibrium is defined the equation
p² + 2pq + q²
where q² = f, frequency of the homozygous recessive allele, p² = f, of the homozygous dominant allele and 2pq is the frequency of the carrier of the dominant + rh blood factor
