Evolutionary and Population Genetics
Population genetics is the study of genetic variation within population, and involves the examination and modelling of changes in the frequencies of genes and alleles in population over space and time. A significant number of the genes found within a population will be polymorphic - that is, they will occur in different structures (or alleles). Numerical models are utilized to examine and predict the occurrence of specific alleles or combination of alleles in population, in view of advancements in the molecular understanding of genetics, Mendel's laws of inheritance and modern evolutionary theory. The focus is the populace or the species not the person. Evolutionary Genetics are the investigation of how hereditary variety prompts transformative change. It incorporates subjects, for example, evolution of genome structure, the genetic basis of speciation and adaptation, and genetic change in response to selection within populations.
