In a given population(A) W11=W12>W22 and  Population (B) W11=W12<W22 , the natural selection will favour;

I- Population A showing directional selection against recessive allele A2, A1 fitness increases

II-Population B showing directional selection against dominant allele A1, A2 fitness increases

III- natural selection rapidly favour population A than population B
