Population bottleneck definition
http://dictionary.sensagent.com/Population%20bottleneck/en-en/ WebGenetic drift can result in genetic traits being lost from a population or becoming widespread in a population without respect to the survival or reproductive value of the alleles involved. A random statistical effect, genetic drift can occur only in small, isolated populations in which the gene pool is small enough that chance events can change its …

During bottlenecks, a population shrinks temporarily and therefore loses genetic variation. Bottlenecks also result from alterations in gene flow such as decreased migration, expansions into new habitats, or population subdivision.
WebDec 28, 2024 · Population bottleneck is one way that genetic diversity may be lost. A population bottleneck is a reduction in the size of a population due to some environmental or biological factor decreasing the number of individuals. This reduction can be temporary or permanent, and it can occur over a short or long period of time.
