Population genetics is a subfield of genetics that deals with genetic differences within and among populations, and is a part of evolutionary biology. Studies in this branch of biology examine such phenomena as adaptation, speciation, and population structure. Population genetics was a vital ingredient in … See more Population genetics began as a reconciliation of Mendelian inheritance and biostatistics models. Natural selection will only cause evolution if there is enough genetic variation in a population. Before the discovery of See more If all genes are in linkage equilibrium, the effect of an allele at one locus can be averaged across the gene pool at other loci. In reality, one allele is frequently found in linkage disequilibrium with genes at other loci, especially with genes located nearby on the same … See more • Allele frequency spectrum • Assortative mating • Balancing selection See more Selection Natural selection, which includes sexual selection, is the fact that some traits make it more likely for an organism to survive and reproduce. … See more Explaining levels of genetic variation Neutral theory predicts that the level of nucleotide diversity in a population will be proportional to the … See more • Population Genetics Tutorials • Molecular population genetics • The ALlele FREquency Database at Yale University See more WebIt has been difficult to identify genes affecting drug response to Selective Serotonin Reuptake Inhibitors (SSRls). We used multiple cross-sectional assessments of depressive symptoms in a population-based study to identify potential genetic interactions with SSRIs as a model to study genetic variants associated with SSRI response.
