"Population genetics is a subfield of genetics that deals with genetic differences within and among populations, and is a part of evolutionary biology."
The study of how genetic variation changes within and among populations over time, including factors that influence allele frequencies and evolution.
"Studies in this branch of biology examine such phenomena as adaptation, speciation, and population structure."
"Its primary founders were Sewall Wright, J. B. S. Haldane and Ronald Fisher."
"Population genetics was a vital ingredient in the emergence of the modern evolutionary synthesis."
"The primary founders of population genetics... also laid the foundations for the related discipline of quantitative genetics."
"Modern population genetics encompasses theoretical, laboratory, and field work."
"Population genetic models are used both for statistical inference from DNA sequence data."
"Population genetic models are used... for proof/disproof of concept."
"What sets population genetics apart from newer, more phenotypic approaches to modelling evolution... is its emphasis on such genetic phenomena..."
"...phenomena as dominance, epistasis, the degree to which genetic recombination breaks linkage disequilibrium, and the random phenomena of mutation and genetic drift."
"This makes it appropriate for comparison to population genomics data." Please note that I have provided the quotes directly related to the questions, but there may be additional information in the paragraph worth exploring.
