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
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…

Hardy-Weinberg Equilibrium and Natural Selection Lab Introduction In this lab we were able to experiment to better understand the concepts of Hardy-Weinberg Equilibrium and Natural Selection. The theory of Evolution states that populations that are evolving will have allele and genotype frequencies that change from generation to generation. To evaluate whether a population is evolving, the Hardy-Weinberg equation is used. A population is in Hardy-Weinberg equilibrium if there is no change in the…

The Hardy Weinberg Principle states that if no evolutionary change is acting on a population, than the allele and genotype frequencies will remain the same. In order for the model to be accurately applied, a population must meet a set of strict requirements. The conditions a population must exceed for the Hardy Weinberg Principle are: no natural selection, no gene…
