Population Genetics

What is Population Genetics?
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population…
Hardy-Weinberg Principle
33.2: Hardy-Weinberg Principle
Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to…
Mutation, Gene Flow, and Genetic Drift
33.3: Mutation, Gene Flow, and Genetic Drift
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five…

33.5: Environment: Protocol for Assessing the Relative Effects of Environment and Genetics on Antler and Body Growth for a Long-lived Cervid
Animals from the same species each display similar characteristics and determining whether they arise from environmental conditions in the wild is…
Immunology and Infection: Forward Genetics Screens
33.6: Immunology and Infection: Forward Genetics Screens
Single-cell multiplex gene expression enables simultaneous analysis of multiple DNA regions and determines population heterogeneity. This…

33.7: Immunology and Infection: Identifying DNA Mutations in Purified Hematopoietic Stem/Progenitor Cells
Stem cells are critical for preserving genomic integrity for the prevention of disorders, disease and aging. This protocol uses the LacI…
