STPM Biology - chapter 18: Revision essay question 2

2, Define the Hardy-Weinberg Law                         

Answer

A principle that in an infinitely large, randomly mating population in which selection, migration and mutation do not occur, the frequencies of alleles and genotypes do no change from generation to generation.
It can be represented by the Hardy-Weinberg equation.
                             p² + 2pq +q² = 1
           where, p = dominant allele frequency
                       q = recessive allele frequency
                       p² = frequency of homozygous dominant in a population
                       q² = frequency of homozygous recessive in a population
                       2pq = frequency of heterozygous in a population
