The system relies on admixture — a genetic principle that argues that when a family migrates across a geographic barrier into a new location, they start mating with the locals; new traits start blending into their gene pool, and this genetic diversity provides a ruler for gauging the distance from home.
This is unusual because invasive species with greater genetic diversity often have a greater chance at survival — a more diverse gene pool means more variety in traits of individuals for natural selection to act upon and allow the species to survive and thrive in a new area.
The groups that evolved into bonobos, chimps, and humans all retained slightly different subsets of this ancestral population's diverse gene pool — and those differences now offer clues today to the size and range of diversity in that ancestral group.
«Our studies clearly show that widespread species have a much more diverse intraspecific gene pool than species that are adapted to a specific habitat,» explains Dr. Jan Christian Habel of the Technical University in Munich, and he continues, «Once these animals — due to the fragmentation of their habitats — lose the opportunity to maintain this genetic diversity by means of exchange, they will no longer be able to adapt to changing environmental conditions in the future.»
Therefore, cloning should never be allowed to become so common that it reduces the overall diversity in the human gene pool.
This hypothesis suggests that high local genetic diversity can exist by drawing variation from a common and relatively limited global gene pool.

As a result, no modern horse population can fully represent the genetic diversity ancestral to the modern, domesticated gene pool (11 ⇓ — 13).
The white - footed mice's success is encouraging from a conservation perspective, since the urban mice were starting with a limited gene pool — only half the genetic diversity of country mice, noted Max Lambert, an urban ecologist and doctoral candidate at Yale University in New Haven, Connecticut, who was not involved in the study.
Dating a person of a different race actually helps with genetic diversity and is only helping to prolong and improve the human gene pool.
In an attempt to inject some healthy diversity back into the breed's gene pool, Swiss breeders have begun crossing the English bulldog with a breed from the US, known as «The Olde English Bulldogge».
To accomplish this Bell says that breeds with small populations (LE list) need a mentoring program for their puppy buyers because healthy gene pools require genetic diversity and the careful selection of sires and dams in order to produce the desired traits and avoid the deleterious mutations that accompany unwanted traits and diseases.
