The small founding populations represented less than half the genetic diversity of the species.
We suggest that what students typically learn during instruction is that genetic drift has a powerful effect in founding populations.
"It's looking more and more as though there were several different founding populations, arriving from different places".
Both clusters exhibited an extremely low genetic diversity, suggesting small founding populations subjected to inbreeding and genetic drift with no, or very limited, genetic influx from population admixture.
Yet those communities have returned as ice has receded, and researchers have long debated just how far the new founding populations have traveled.
The map will be useful for studies of diseases, including prostate and breast cancer, diabetes, hypertension, and end-stage renal disease, that have large differences in incidence between the founding populations of either Hispanics or African Americans.
Where was the source of founding populations for Clovis people?" It is possible that alternative approaches to inferring prehistoric demography and population origins may come from alternative data and analytical approaches.
Moreover, the alternative simulations are also not concordant with respect to underlying assumptions about the viability of small founding populations, requirements for founding population sizes, migration rates, etc. (Moore and Moseley 2001; Anderson and Gillam 2001).
Disease-gene discovery using mapping by admixture linkage disequilibrium (MALD) requires a map of polymorphic markers that differentiate between the founding populations, along with differences in disease-gene allele frequencies.
This conversion can actually lead to increased variance in the founding populations which then allows for rapid adaptive evolution.
The taxonomic identity of feral raccoons inhabiting Eurasia is unknown, as the founding populations consisted of uncategorized specimens from zoos and fur farms.
