Exam 3 Study Guide: BSC2010, Fall 2024 Exam 3 will consist of 33 questions that will focus on the material covered in lecture. The assigned reading will help to clarify this material by providing further clarification, examples, and background. Topics or definitions that were not presented in lecture will not appear on the exam. You will not need, nor can you use, calculators for the exam. Processes: You should be familiar with gene flow, genetic drift (including the bottleneck effect and founder effect), mutation, natural selection, sexual selection, allopatric and sympatric speciation, and convergent and divergent evolution. p2 + 2p9+ q2 = 1 Concepts or theories: You should be familiar with the Endosymbiotic Theory, the Hardy-Weinberg p+a = Theory, the Red Queen Hypothesis, and Kimura’s Neutral Theory. coero. arms race genetic variation b/C neutral mutation Numerical problems: You should be prepared to solve Hardy-Weinberg problems (using the two equations that you are expected to know) and Mendelian genetics problems using Punnett squares. Graphical analyses: You should be prepared to interpret graphs/visual representations of data including phylogenetic trees and character tables. 1859 Dates and names: You should know the names and dates of the major scientists (Darwin, Wallace, 1983 taxonomy , neutral Kimura, Linnaeus, Margulis, Mendel) and their contributions presented in lecture, the major theory of 100sbinom. nomenclature evo evolutionary transitions presented in lecture, and the major dates with respect to human evolution. In the lectures on human evolution and the origin of life, I will provide more specificity as to which dates you should know. Definitions: You should know all of the terms introduced in lecture including the Biological Species analogous silent Concept, neoteny, homoplasy, heterochrony, analogous and homologous traits, synonymous and dN nonsynonymous substitutions, fitness, and the different types of selection covered in lecture. missense 0 - 1 *Note that the items listed above are not intended to be an all-inclusive list of the material to be covered in the exam. To fully prepare, I recommend you review all lectures carefully, and review your notes. I also recommend considering examples of the relevant processes/concepts and comparing and contrasting these where appropriate. posts pre mech affects pheno /Pavers Chapter 13: Processes of Evolution p+ a = Hardy-Weinberg P2pg q: Egenotype fe and bir evolution descent u/ modification : Theorem : + environmental change phenotypic change - naturalselection:differental reproductivesuccess(creates adaptations set homologous structures vs analogous structures (nomoplasy) common ancestor no common ancestor - - similar anatomy dissimilar anatomy - - similar/dissimilar function similar functions - - DarwinpublishedOnthe Origin of Species" a a fitness : heritable individual variation contribution to next fitness ero.. 10 or 1) contribution gen relativeofto the bio ero can occur in the absence of natural selection ↳ adaptations others (tratagriredfrom ↑. logenetic drift - random alle -> no selective pressure from environment is is freg changes. natural selection directly acts on phenotype If both phenotypes are present over the longterm Phenoratios , are about =; similar reproductive success what causes micro-evolution : changes in alle freg gene freg gene pool within populations , , -natural selection - mutation genetic diversity within flow b/w but increases -gene immigration/emigration; reduces variability populations one : -genetic drift chance events that reduce genetic variation : ↳ : population ↳ bottleneck effect founder effect : small subset of population establish new colony assortative similar to self : - Sexual selection natural selection for : reproductive successmating dissasortveditt ; nonrandom parrises b/c asymmetrical investment in moring
