BigIdea Investigation 2 S25 Evolution 1 INVESTIGATION 2 MATHEMATICAL MODELING: HARDY-WEINBERG* How can mathematical models be used to investigate the relationship between allele frequencies in populations of organisms and evolutionary change? Manitou 634 Workshop Manual download. ? BACKGROUND Evolution occurs in populations of organisms and involves variation in the population, heredity, and di!erential survival. One way to study evolution is to study how the frequency of alleles in a population changes from generation to generation. In other words, you can ask What are the inheritance patterns of alleles, not just from two parental organisms, but also in a population? You can then explore how allele frequencies change in populations and how these changes might predict what will happen to a population in. CHAPTER 23 THE EVOLUTION OF POPULATIONS OUTLINE I. Population Genetics A.

The modern evolutionary synthesis integrated Darwinian selection and Mendelian inheritance B. The genetic structure of a population is defined by its allele and genotype frequencies C. The Hardy-Weinberg theorem describes a nonevolving population II. Causes of Microevolution A. Microevolution is a generation-to-generation change in a population's allele or genotype frequencies B. The five causes of microevolution are genetic drift, gene flow, mutation, nonrandom mating, and natural selection III.

Genetic Variation, the Substrate for Natural Selection A. Genetic variation occurs within and between populations B. Mutation and sexual recombination generate genetic variation. Chapter 24 The Origin of Species Lecture Outline Overview: That?Mystery of Mysteries? Darwin visited the Gal?pagos Islands and found them filled with plants and animals that lived nowhere else in the world. He realized that he was observing newly emerged species on these young islands.
