Biology 171 Fall 2011 Discussion Objectives Relevant to EXAM 3 Week 8: Explaining and predicting genotype and phenotype frequencies 1. Relate meiosis to inheritance patterns 2. Use genetics principles to create hypotheses (quantitative models) to explain observations regarding genotype and phenotype frequency 3. Use genetics principles to create predictions of outcomes of crosses, including predictions of frequencies of genotypes and phenotypes 4. Use quantitative reasoning (specifically probability rules) to predict and explain patterns of inheritance Week 9 (also reviewed in Week 10): Deviations from HWE 1. find allelic and genotypic frequencies in non-Hardy-Weinberg equilibrium populations when given partial information about these frequencies. 2. find allelic and genotypic frequencies in Hardy-Weinberg equilibrium populations

Unformatted text preview: when given partial information about these frequencies. 3. make qualitative predictions about allelic and genotypic frequencies of populations in 1) Hardy-Weinberg equilibrium 2) undergoing genetic drift 3) undergoing selection. 4. justify their predictions based on theory (Hardy-Weinberg equilibrium, drift, selection). Week 10: Evolution in Sticklebacks 1. Interpret Mendelian ratios of traits in a real research situation. 2. Interpret mRNA as an indicator of transcribed DNA and likely protein synthesis (translation) 3. Hypothesize how a major evolutionary change could occur through a mutation in regulatory DNA 4. Hypothesize proximate and ultimate causes for morphological differences 5. Communicate the relationship between DNA, transcription, translation, phenotype, and proteins...
