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 …show more content…
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
2 = 1 p
2pqas a heterozygous genotype and q as a homozygous recessive genotype (Roberts & Reiss,
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 deviation and linear regression by creating my own version of this graph:
Evolutionary Forces. (2014)
Since Census at School survey had four options for eye colour: blue, brown, green and other, while my survey had only blue, brown and green, for simplicity p will correspond to the allele for brown eyes as it is dominant. Leaving qas the recessive alleles of blue, green and other.
Properties of HW Law on Observed Eye Colour
1) Per school year census from Census at School, each student involved is a trial, therefore there is a fixed number of n trials per school year.
2) By assumption that each student per school year is chosen randomly, the eye colour of
