Population Genetics

What is Population Genetics?
A population is made up of interbreeding members of the same species that simultaneously live in an area. When the individuals in a population breed,…
Hardy-Weinberg Principle
33.2: Hardy-Weinberg Principle
Diploid organisms have two alleles of each gene that are located on their somatic chromosomes, one copy from each parent. Therefore, each member of a…
Generation of Genetic Variation
33.3: Generation of Genetic Variation
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles can change over time. Therefore, any deviations in the five…
Surveying Genetic Variation in Populations
33.4: Surveying Genetic Variation in Populations
An important topic in the field of population genetics is speciation, the process by which populations become distinct species. Studies like this one…

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…
