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.. 8.5. Starter. What is the term for all the alleles of all the genes in a population?. Gene Pool. What do you think the term would be for the number of times an allele occurs within a gene pool?. Allelic Frequency. 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. 8.5. Starter. What is the term for all the alleles of all the genes in a population?. Gene Pool. What do you think the term would be for the number of times an allele occurs within a gene pool?. Allelic Frequency. 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.. Pre-Class Exercise . Learning Objectives. By the end of this session, students should be able to…. Illustrate how historical human migration patterns have contributed to genetic variation observed in modern populations.. Pre-Class Exercise . Learning Objectives. By the end of this session, students should be able to…. Illustrate how historical human migration patterns have contributed to genetic variation observed in modern populations.. 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. Population genetics. : focuses on genetic changes within an interbreeding population.. Gene pool = _______________________________. Allele Frequency . =. all the genes in a population . Shows frequency of . What is Population Genetics?. Describes allele and genotype frequencies in populations over space and time. Models evolutionary forces (survival, mutation, migration, etc.). Models are generally limited to one or a few loci. 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. Using mathematical approaches to calculate changes in allele frequencies…this is evidence of evolution.. Hardy-Weinberg equilibrium. Hypothetical, non-evolving population. preserves allele . frequencies. individuals in that population that possess a certain allele is called the allele frequency. Populations can have allele frequencies, but individuals cannot. This makes populations a reasonable hier
