Founder Effect. The Founder Effect is defined as a type of bottleneck, a type of genetic drift describing the loss of the allelic variation that accompanies founding of a new population from a very small number of individuals (a small sample of a much larger source population).
For example, two well drilling companies -- one in Pennsylvania and one that covers New Hampshire, Vermont and central Massachusetts -- state the cost for drilling a well and outfitting it with pump equipment averages between $5,000 and $7,000, at the time of publication.
The well and necessary supplies, such as the well pump, range from $1,000 to $5,000, in addition to the cost per foot for drilling and any necessary permits or fees. The septic tank, cost of excavation to bury the tank, and pipe for the septic system range from $5,000 to $30,000, depending on the region. Learn more about Building Materials
