 * Sewall** **Wright** was an //American geneticist// known for work on evolution and path analysis. Along with R.A. Fisher and J.B.S. Haldane, Wright was founder of theoretical population genetics and discovered the inbreeding coefficient, which serves as a measure for the level of blood relation between two given individuals. He extended his work to populations, computing amount of inbreeding between members of populations as a result of genetic drift, which in the change in the frequency of a gene variant in a population due to random sampling. He and Fisher created methods for calculating the distribution of gene frequencies among populations as a result of the intervention of natural selection, mutation, migration, and genetic drift. His work with Fisher and Haldane is recognized as a major step in the development of the modern synthesis of genetics with evolution in the evolutionary theory. He also, over his years, made major contributions to genetics of mammals and biochemical genetics.
