PPT-LO 1.7 : The student is able to justify data from mathematical models based on the Hardy-Weinberg

SP 21 The student can justify the selection of a mathematical routine to solve problems Explanation The HardyWeinberg equation describes allele frequencies in populations and how evolution occurs In order for ther. Taylor Pruett. AP biology. 3. rd. block. British mathematician Godfery H. Hardy and German physician Wilhelm Weinberg.. Who are Hardy and Weinberg?. In 1908, Hardy and Weinberg came up with a mathematical model to estimate the genotypic frequencies of a population that is in genetic equilibrium.. Microevolution is a change in allele frequencies or genotype frequencies in a population over time. Genetic equilibrium in populations: the Hardy-Weinberg theorem. Microevolution is deviation from Hardy-Weinberg equilibrium. Hardy-Weinberg conditions Gene and Genotypic frequencies. The Hardy Weinberg law states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.. .. Evolutionary Forces. Mutation (random). Genetic Drift (random). Gene Flow (random). Sexual Selection (non-random). Genetic Drift. Random, non-selective, changes in allele frequency due to chance. . A population consists of 9% white sheep and 91% black sheep. If the black-wool allele is dominant and the white-wool allele is recessive, what is the frequency of the black-wool allele?.

No two people are exactly the same. How is this possible?. What causes variation?. The current population of planet Earth is more than . 7 billion people!. Causes of variation. Using mathematical approaches to calculate changes in allele frequencies…this is evidence of evolution.. Hardy-Weinberg equilibrium. Hypothetical, non-evolving population. preserves allele . frequencies. Gene pool. Allele frequencies. DEFINITIONS. Gene pool. All the alleles of all the genes of all the individuals of an entire population. Allele frequencies. The number of times an allele for a particular gene occurs within a gene pool. Reflects the frequency of alleles in a population of organisms under ideal conditions.. . 64NB. p. 2. + 2pq + q. 2. = 1. p + q = 1. Hardy Weinburg Equilibrium.
