Alleles for gene I are I^(A),I^(B) and I^(O) . If I^(A) and I^(B) are dominant over I^(O) , the I^(A)=I^(B) gt I^(O) indicates

[A]: According to Hardy-Weinburg law both gene frequencies and genotype frequencies will remain constant from generation to generation 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.
