The coagulating power of electrolytes having ions $$Na^{+},\ Al^{3+}$$ and $$Ba^{2+}$$ for arsenic sulphide sol increases in the order:
In Hardy-Weinberg equation, the frequency of heterozygous individual is represented by
Hardy-Weinberg equation is $$p^2$$ + 2pq + $$q^2$$ = 1. Here, p is the frequency of the "A" allele and q is the frequency of the "a" allele in the population. Thus, $$p^2$$ represents the frequency of the homozygous genotype AA, $$q^2$$ is the frequency of the homozygous genotype aa, and 2pq represents the frequency of the heterozygous genotype Aa.
The coagulating power of electrolytes having ions $$Na^{+},\ Al^{3+}$$ and $$Ba^{2+}$$ for arsenic sulphide sol increases in the order:
