Lecture Synopsis
This lecture provides an introduction to population genetic methods salient to describing genetic diversity, structure, and the estimation of gene flow. More specifically, it covers:
1. Expectations for genetic structure and diversity given landscape context:
Drift/migration
Effective population size
2. Models underlying population genetic inferences
Mutation models
Demographic models
3. Considerations for study design
4. Specific metrics used in landscape genetic studies
5. Estimating gene flow
If you are unfamiliar with genetic terminology, types of DNA (mtDNA, nDNA, chloroplast), genetic methods, Hardy-Weinberg equilibrium, linkage equilibrium, genetic drift, and effective population size, we suggest you watch the genetics tutorial before watching this lecture.
