founder effect
a high frequency of a particular allele in a population founded by a small ancestral group when one or more of the founders was a carrier of that allele ...
Founder Effect
The founder effect is the reduction in genetic variation that results when a small subset of a large population is used to establish a new colony.
founder effect The difference in gene pools between an original population and a new population founded by one or a few individuals randomly separated from the original population, ...
founder effect
A cause of genetic drift attributable to colonization by a limited number of individuals from a parent population.

Founder effect A high frequency of a particular allele in a population caused by it having been present in one or more members of a small number of individuals from whom the population is descended.
[edit] Founder effect
The field of biodiversity research (inevitably) suffers from natural human egocentric "myopic" cognitive biases. It has often been criticized for being overly defined by the personal interests of the founders (i.e.
Founder effect
Genetic drift observed in a population founded by a small non representative sample of a larger population.

founder effect Changes in gene frequency that occur when a few individuals from a parental population colonize new habitats; the change is a result of founding individuals not having a representative sample of the parental population's genes.
"The founder effect is probably responsible for the virtually complete lact of blood group B in American Indians, whose ancestors arrived in very small numbers across the Bering Strait during the end of the last Ice Age, about 10,000 years ago.
The founder effect is a case of genetic drift in which rare alleles, or combinations of alleles, occur in higher frequency in a population isolated from the general population.
founder effect
These factors may produce distinct subpopulations on the different islands. So long as they remain separate (allopatric) we consider them races or subspecies.
Changes in allele frequency that result because the genes appearing in offspring are not a perfectly representative sampling of the parental genes. (eg. in small populations). See also founder effect.
Population bottlenecks can dramatically reduce genetic diversity by severly limiting the number of reproducing individuals and make inbreeding more frequent. The founder effect can cause rapid, ...
This "sampling error" leads to the founder effect: rapid changes in allele frequencies in the colonizing population and divergence from the parent population.
