Nature Genetics - Catching the (genetic) drift. Skip to main content. Thank you for visiting nature.com. ... Few book-length treatments have attempted to encapsulate the entire field.

Population bottlenecks imply a reduction in effective population size, the increase of sample variance across generations, that is, random genetic drift. As population size drops the stochastic change ...

This happens because of a process known as random genetic drift, says Dr Wilson, whereby some genetic variants become more common and others are lost.

Random genetic drift has certainly played a big role in human evolution. Human populations were tiny until around 10,000 years ago, and went through a major bottleneck around 2 million years ago.

Genetic Drift and the Founder Effect: Eastern Pennsylvania is home to beautiful farmlands and countryside, but it's also a gold mine of information for geneticists, who have studied the region's ...

My colleagues and I have for the past 15 years been investigating genetic drift in the populations of the cities and villages in the Parma Valley in Italy. We have examined parish books, ...

In this case, the gene could have reached the 40 per cent level by chance alone – a process known as genetic drift. So knowing the frequency of a gene alone does not tell you whether natural ...
