PPT-HARDY-WEINBERG WARM UP #2

A population consists of 9 white sheep and 91 black sheep If the blackwool allele is dominant and the whitewool allele is recessive what is the frequency of the blackwool allele HARDYWEINBERG WARM UP 2. 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.. ..

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. 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.
