During the first two decades of Governor Wentworth's term New Hampshire had been beset with Indian troubles. With little aid from England, then at war with its old-time enemy, France, the colonists undertook the sieges of Louisbourg, and helped to reduce Crown Point, and in the conquest of Canada. By the time of the signing of the Peace of ...In 1760 there were 70,000 residents in the areas of Canada which were under French rule. A substantial fraction of these derived from the much smaller 17th century founding population. Today the number of North Americans with some known French Canadian ancestry numbers around ~10 million.

It produces a high frequency of some rare alleles in a small isolated population. The Founder Effect occurs when a population is subjected to near extinction and then recovers so that only a few alleles are left in survivors.After ten lions were reintroduced in 2005, the population has recovered to over 200 lions in 2016. Although the increase of lions in the SVC seems promising, a question remains whether the population is genetically viable, considering their small founding population. ….

This founding population constituted of adult individuals, at the mutation-selection equilibrium, with a balanced, stochastic sex-ratio. Then, in each year, a proportion R r of captive newborns was released to the wild (Binomial process).We also typed 2–4 offspring from each of the ten founding pairs as well as 15 individuals collected from the original wild source population in 2012. Using the Uneak pipeline contained within the program Tassel [ 19 – 20 ] we simultaneously identified SNPs within the randomly sequenced tags and assigned individual genotypes.
Founder effect can result in the smaller population that left the larger population to have less genetic diversity.
