Foundations: Mendelian Genetics and Probability
1-2 weeksReview Mendelian inheritance (dominance, segregation, independent assortment), basic probability, and the chi-square test. Understand how alleles are transmitted from parents to offspring and how genotypic ratios arise.

Hardy-Weinberg Equilibrium and Allele Frequencies
1-2 weeksLearn to calculate allele and genotype frequencies, apply the Hardy-Weinberg equation (p^2 + 2pq + q^2 = 1), test for departures from equilibrium using chi-square tests, and understand the five assumptions of HWE.
Genetic Drift, Bottlenecks, and Founder Effects
2-3 weeksStudy stochastic processes in finite populations: the Wright-Fisher model, effective population size, fixation probability, bottleneck and founder effects. Use simulations to visualize drift in action.
Natural Selection at Single Loci
2-3 weeksModel selection on single loci: fitness, selection coefficients, directional selection, overdominance, underdominance, and frequency-dependent selection. Derive equilibrium allele frequencies under different selection regimes.
Mutation, Migration, and Combined Forces
2-3 weeksAnalyze mutation-selection balance, mutation-drift balance, migration-selection balance, and the island model of migration. Understand how multiple evolutionary forces interact to determine allele frequencies.
Population Structure and Inbreeding
2-3 weeksStudy F-statistics (FIS, FST, FIT), the Wahlund effect, inbreeding coefficients, identity by descent, inbreeding depression, and Wright's island model. Analyze population structure using real data.
Coalescent Theory and Molecular Population Genetics
3-4 weeksLearn coalescent models, the neutral theory of molecular evolution, molecular clock, tests of neutrality (Tajima's D, McDonald-Kreitman test), selective sweeps, and background selection.
Genomics Era: GWAS, Admixture, and Applied Population Genetics
3-4 weeksApply population genetics to modern genomics: genome-wide association studies, admixture mapping, population genomics, conservation genetics, forensic genetics, and detecting signatures of selection in genome data.
