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

CHAPTF,F.24 THE ORIGIN OF SPECIES OUTLII\E L What Is a SPecies? A. The biological species concept emphasizes reproductive isolation B. prezygotic and postzygotic barriers isolate the gene pools of biological species C. The biological species concept does not work in all situations D. Other species concepts emphasize features and processes that identiff and unite species members II. Modes of SPeciation A. Geographical isolation can lead to the origin of species: allopatric speciation B. A new species can originate in the geographical midst of the parent species: sympatric sPeciation c. Genetic change in populations can account for speciation D. The punctuated equilibrium model has stimulated research on the tempo of speciation The Origin of Evolutionary NoveltY

Katie Hallstead Mrs. Legary AP Biology p.0 January 15, 2013 Lab 4: Plant Pigment and Photosynthesis Abstract In this experiment, there are two activities that aim to find two different things. In the first one, paper chromatography is used to separate the pigments found in chlorophyll. The second activity consists of measuring the rate of photosynthesis by observing the change in color that happens when DPIP is reduced through a time interval. Problem How many pigments exist within plants, and at what rates do they photosynthesize when exposed to different lights? Hypothesis

Sex Linked genes -The X and Y chromosomes determine the sex of an individual and contain genes related to female and maleness. All other genes on these chromosomes are called sex linked genes -The X chromosome has the most genes but in some species (fruit fly), genes are found on the Y chromosome as well. genes on the Y chromosome are only passed from father to son -Sex linked gene inheritance (x linked) can be studied using fruit flies. The gene for eye color is located on the X chromosome. R-Red eyes are dominant to r white eyes. -Alleles carried on the X chromosome are shown as X^R, and X^r, Females have 2 alleles (X^R X^R, X^R X^r, or X^r X^r) while males only have one (X^R Y, or X^r Y) The male?s phenotype results from one X allele plll.

13. Explain how transport proteins are similar to enzymes. The transport proteins of the plasma membrane are similar to enzymes in that they sometimes catalyze one of a number of steps of a metabolic pathway. 14. Explain how transport proteins facilitate diffusion.
