Such studies are based on the premise that afoundereffectis present and detectable.
From theCambridge English Corpus
The residents of enclaves may be expected to differ somewhat from the homeland population due to thefoundereffectand subsequent genetic isolation.
From theCambridge English Corpus
However, thefoundereffectignores the possibility that other non-reproductive life stages as well as males also balloon, contributing significantly to the aerial population.
From theCambridge English Corpus
A selective sweep caused by the spread of a favourable mutation through a large population has similar effects on neutral diversity to afoundereffect.
From theCambridge English Corpus
If so, the 'magnification' of afoundereffectcould produce the observed frequencies.
From theCambridge English Corpus
Dominant conditions with low reproductive fitness show little regional variation in frequency, but milder conditions may show variation as a result offoundereffector genetic drift.
From theCambridge English Corpus
Recurrent introduction,foundereffect, random genetic drift, and/or selection pressure caused by biotic and abiotic factors would also contribute to the final genetic make-up of the introduced population.
From theCambridge English Corpus
One possible interpretation is that northern populations might not have experienced a strong bottleneck, but the observed low genetic variability could simply reflect afoundereffect.
From theCambridge English Corpus
First, the so-calledfoundereffectoccurs when founder populations bring only a subset of the genetic variation from their ancestral population.
