TitlePopulation Genetics and Evolution:Hardy Weinberg EquationII. HypothesisThis lab is separated into four different cases. Within each of these cases, there areaspects that change the allele frequency within a population (this will be more deeply explainedin the analysis).The first case represents the Hardy-Weinberg equilibrium. In this case, I hypothesizethat the allele frequencies should end up with no alterations from the original frequencies. Myhypothesis is based on the Hardy-Weinberg theorem.The second case is similar to the first case, except natural selection is present. Becauseof this natural selection, all of the homozygous recessive animals die, and therefore will lower thefrequency of the recessive allele, I hypothesize.Case three is like case two, except, now not only can the homozygous recessive notsurvive, but the homozygous dominant have only a statistical chance of 50% of surviving. Therefore, I hypothesize that the frequency of the dominant allele will rise, but not as greatly asin case two.Case four is supposed to represent genetic drift. In order to represent genetic drift, onemust determine the frequencies of a population, and then isolate a specific group, and thenrecording the frequencies again generations later. I hypothesize that in this lab the differentgroups will not equally represent the gene pool and therefore the frequencies may be drasticallydifferent from the original populations frequency. The actual frequency change, however, isunpredictable because it is random....
