Population Genetics
Manage episode 433100048 series 2770060
In this episode, we discuss population genetics and see how genetically related individuals share the same alleles, delving into the mechanisms of gene flow and genetic drift. We'll also unravel the complexities of hybrid vigor, reproductive isolation, and natural selection, and how these processes shape the genetic landscape of populations.
We'll also touch on the fascinating dynamics of X-linked and mitochondrial inheritance, and the role of genomic imprinting in disease risk. Ever wondered how the Hardy-Weinberg equation helps us understand genetic equilibrium in populations? We've got that covered too, breaking down the assumptions and applications of this essential model. Plus, we'll delve into how allele frequencies can shift due to factors like mutations and population bottlenecks.
