The study of genetic variation and its causes within populations. Population structure • The proportions of individuals in a population belonging to different age classes (age structure). Also, the distribution of the population in space.
The study of the genetics of groups of individual organisms, often shown through the graphic of a haplogroup or phylogenetic tree.
A field of genetics that studies genetic variation and genetic evolution of populations.
The study of the movements and effects of genes within populations and gene pools.
the study of how genetic principles apply to entire generations.
The study of factors affecting gene and genotypic frequencies in a population.
The study of hereditary at the population level. This may include measurement of allele frequencies and the genetic relationships between members of the group.
The study of variation in genes among a group of individuals.
The branch of genetics that deals with frequencies of alleles and genotypes in breeding populations.
Population genetics is the study of the allele frequency distribution and change under the influence of the four evolutionary forces: natural selection, genetic drift, mutation, and gene flow. It also takes account of population subdivision and population structure in space. As such, it attempts to explain such phenomena as adaptation and speciation.
