Welcome to My AP Biology Thoughts podcast, my name is Nikki and I am your host for episode #6 called Unit #7 Evolution: Hardy Weinberg Equilibrium.. Today we will be discussing the conditions for a Hardy Weinberg equilibrium, the importance of it, and the equation used to find the characteristics of itSegment 1: Introduction to Hardy WeinbergHardy Weinberg is the use of equations to find out allele and genotype frequencies in a population if Evolution didn’t occur. This allows us to see what the population should look like without evolutionDominant vs recessive(p or q)P and qq^2 and q^2p+q+1p^2+q^2+2pq=1Segment 2: More About the Hardy Weinberg TheorySo when do we use these equations? Well to use Hardy Weinberg, there can’t be any evolution taking placeLet's remember the 5 fingers of evolutionGenetic drift- little genetic variation, random non-adaptive changes due to random eventBottleneck or foundersNo random events and no migration to new areasBison being hunted and now little genetic variationNon-random mating/ sexual selectionPeacocks with larger and brighter feathersMutationsMutation changing fur color to a totally different colorGene flow-bring alleles togetherPurple birdNatural selection-non-random adaptive changesfinchesUncoincidentally the 5 requirements for Hardy Weinberg isNo genetic driftNo sexual selectionNo mutationsNo gene flowNo natural selectionSegment 3: Connection to the CourseHow does this topic fit into the greater picture of evolution?This topic helps us see a population without evolutionThen, comparing to the actual population with evolution, and there are differences between the hardy weinberg and actual, that shows evidence of evolution as well as how evolution effects
