Founding population - Established in 1732, with settlement in Savannah in 1733, Georgia was the last of the thirteen colonies to be founded. Its formation came a half-century after the twelfth British colony, Pennsylvania, was chartered (in 1681) and seventy years after South Carolina’s founding (in 1663).

The rate of loss in genetic diversity in collections or populations is directly related to management decisions (Ballou et al. 2010 ).In population genetics, the founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population. It was first fully outlined by Ernst Mayr in 1942, [1] using existing theoretical work by those such as Sewall Wright. [2] In 1950, five years after the founding of the United Nations, world population was estimated at around 2.6 billion people. It reached 5 billion in 1987 and 6 in 1999.
