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.. Falconer & Mackay, chapters 1 and 2. (1.5. , 1.6, 2.5, and 2.6). Sanja Franic. VU University Amsterdam 2011. 1.4. As an exercise in algebra, work out the gene frequency of a recessive mutant in a random-breeding population that would result in one-third of normal individuals being carriers.. 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. 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. . weinberg. practice . Changes in allele frequencies. Turn in: Comparing AA WS and video notes. Homework.

Phenotype Frequency. Total genetic information in a population. Portion of gene copies of a given allele. Wilhem Weinberg. (1862 – 1937). Gregor Mendel. G. H. Hardy. (1877 - 1947). (1822-1884). Lectures 4-11: Mechanisms of Evolution (Microevolution). Hardy Weinberg Principle . (. Mendelian. Inheritance). Page 400. A. Hardy-Weinberg Principle. 1. States that allele frequencies in a population will remain constant unless one or more factors cause those frequencies to change.. A. Hardy-Weinberg Principle. Patterns of inheritance. Starter . 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. Chapter 11 Biology Textbook. KEY CONCEPT . Hardy-Weinberg equilibrium provides a framework for understanding how populations evolve.. . Hardy-Weinberg equilibrium describes populations that are not evolving. . 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.
