प्रश्न
Give a mathematical expression for Hardy Weinberg's principle.
Advertisements
उत्तर
p2 + 2pq + q2 = 1 where 'p2' represents the frequency of the homozygous dominant genotype (AA), '2pq' the frequency of the heterozygous genotype (Aa) and 'q2' the frequency of the homozygous recessive genotype (aa).
