Hardy­Weinberg Law
Given the mathematical and statistical methods used already, this law also uses probability, however is represented in a graphical manner. Through this graph I will determine if the class data set has significant variation on an allele by genotype graph by comparing their points to the collection of data sets from Census at School that will represent in this paper as the Canadian average. The Hardy­Weinberg Law, developed by G.H Hardy and Wilhelm Weinberg in 1908, states that the frequencies of genes and genotypes within a population within a population remain constant if there is an absence of external forces (Roberts & Reiss, 2000, pg. 640). These forces include no mutation, natural selection, genetic drift or migration (Roberts & Reiss, 2000, pg. 640). The
H­W law is comprised of allele frequency (fraction of the population with the given allele), and genotype frequency (the fraction of the population with the given genotype).
The allele frequency equation is p + q = 1, with p as the frequency of the dominant allele, and q as the frequency of the recessive allele. These two allele frequencies result in the genotype frequency equation: p pq ,with representing a homozygous dominant genotype,
2 + 2 + q

2000, pg. 640).
The comparison of my class’s data set and the Census at School as the expected Canadian population will be done by finding the standard…
