MeSH definition : A phenomenon that is observed when a small subgroup of a larger POPULATION establishes
itself as a separate and isolated entity. The subgroup's GENE POOL carries only a
fraction of the genetic diversity of the parental population resulting in an increased
frequency of certain diseases in the subgroup, especially those diseases known to
be autosomal recessive.;
