In 1859, Charles Darwin documented that evolution of life on Earth had taken place and proposed the idea that natural selection was to blame in his book, The Origin of Species (Leicht and McAllister, 2016). Darwin’s findings arose from the different heritable traits, which lead to differences among alleles in a population. Genetic variation is the differences in genetic frequencies in a population and is the basis of evolution. The Hardy Weinberg Principle was developed to test for genetic variation in a given population. 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 flow, no genetic mutation, random mating, and an infinite population size. Due to these near impossible requirements, the Hardy Weinberg Principle can serve as a null hypothesis and be used to predict the expected genotype frequencies from allele frequencies and The objective of our experiment was to determine whether the Hardy Weinberg Principle fit within the Foundations of Biology class population by closely examining variations in the target loci, PV92 and TAS2R38. Chemical phenylthiocarbamide (PTC) is known to produce a very bitter taste. The TAS2R38 gene, located on chromosome 7,…
