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.. What you should know:. The ‘etiquette’ used to represent genetic crosses.. Know what is, and how to represent a monohybrid cross.. Know what is, and how to represent a cross showing sex-linkage.. DNA polymorphism produced by differential folding (intra-molecular interaction) of single-stranded DNA harboring mutations (Orita et al. 1989).. Assays are performed using heat-denatured PCR-amplified DNA on non-denaturing DNA sequencing gels.. Changing Chapter 15 Changing Allele Frequencies 1.Mutation–introduces new alleles into 2.Natural Selection–specific alleles are 3.Non-random Mating–individuals of one –Think of 8.7. Starter. What is speciation?. The evolution of new species from existing species.. Learning Objectives. Define speciation. Describe geographical isolation. Explain how geographical isolation can lead to the formation of new species. In-build . mechanisms for adaptation. (or evolutionary mechanisms). Biology Stage 3. Text: Chapter 23. Human Biology Stage 3 . Text: Chapter 15. Key ideas. Population genetics. Observable facts. Natural selection. Other Patterns of Inheritance. Not all genes show a simple pattern of inheritance…. Many genes have more than two alleles. Many traits are controlled by more than one gene. Complete Dominance. Definition: . A) is movement of alleles from one population to another. B) counts as true gene flow only if immigrant individuals breed within their new population. C) makes populations more similar genetically. D) decreases Fst. What you need to know. Ahmed . Rebai.
