The founder effect is a particular example of the influence of random sampling. It was defined by Ernst Mayr as: ... • An established population may fluctuate in size: the founder effect occurs when the population passes through a 'bottleneck' in which only a few individuals survive, and later expands again under...

A small population of insects on an island are predominantly colored yellow, and only a few are red. ... A freak storm destroys most of the insects indiscriminately. ... Just by chance, a high proportion of the survivors happen to have the allele for red coloring with the result that when the population size recovers,

Founder effects; A founder effect occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have:

Another example of genetic drift is known as the founder effect. In this case a small group breaks off from a larger population and forms a new population. This effect is well known in human populations;

The syndrome is common in the Amish because of the "founder effect." ; When a small part of a population moves to a new locale, or when the population is reduced to a small size because of some environmental change, the genes of the "founders" of the new society are disproportionately frequent in the resulting population.

In the present study of 495 Y chromosomes of Ashkenazim, 57 (11.5%) were found to belong to R-M17. Detailed analyses of haplotype structure, diversity and geographic distribution suggest a founder effect for this haplogroup, introduced at an early stage into the evolving Ashkenazi community in Europe.

However in many families, including those from North America demonstrating a genetic founder haplotype, no sequence mutations have been detected. We report an intragenic 38 Kb SEPT9 duplication that is linked to HNA in 12 North American families that share the common founder haplotype.
