[A]: According to Hardy-Weinburg law both gene frequencies and genotype frequencies will remain constant from generation to gen- eration in an infinitely large interbreeding population. [R]: Alleles segregating in a population tend to establish an equilibrium with reference to each other, thus maintain both frequencies constant.
