Population Genetics

 The collection of all the alleles of all of the genes found within a freely interbreeding population is known as the gene pool of the population. It is the study of genetic variation within populations, and involves the examination and modelling of changes in the frequencies of genes and alleles in populations over space and time. Many of the genes found within a population will be polymorphic - that is, they will occur in a number of different alleles. Population genetics is the study of the distribution and change in frequency of alleles within populations, and as such it sits firmly within the field of evolutionary biology. The main process of evolution  are natural selection, genetic drift, gene flow, mutation, and genetic recombination and they form an integral part of the theory that underpins population genetics. Genetics in this branch of biology  which examines such phenomena as adaptation, speciation, population subdivision, and population structure. Population genetics deals with the frequency and interaction of alleles and genes in populations. A genetic population is a set of organisms in which any pair of members can breed freely together. This implies that all members belong to the same species and are located near each other. Each member of the population receives its alleles from other members of the gene pool i.e. parents and passes them on to other members of the gene pool i.e. it’s offspring. Population genetics is the study of the variation in alleles and genotypes within the gene pool, and how this variation changes from one generation to the next. Population genetics is also the most widely misused area of human genetics, sometimes bordering on "vigilante genetics. Population genetics is concerned with gene and genotype frequencies, the factors that tend to keep them constant, and  tends to change them in populations. It is largely concerned with the study of polymorphisms. It directly impacts counselling, forensic medicine, and genetic screening.
