genetic drift may occur when a small group of individuals colonizes a new habitat
Genetic drift occurs in all finite populations. However the effects of drift are more pronounced in smaller populations than in large ones. Meanwhile, even though they are more present in smaller populations, the drifting is more likely to occur in larger populations because of the larger number of different genetic combinations present. Throughout evolution of populations, genetic drifting effects all types of population sizes, though it is more likely in larger populations but more present in smaller populations.
The population needs to be small is the necessary condition for genetic drift to have a significant effect on populations.
Random changes.This would be called genetic drift.
false... its likely to occur in small population
Genetic drift has a larger effect on smaller populations.
Genetic drift may occur when a small group of individuals colonizes a new habitat. These individuals may carry alleles in different relative frequencies than did the larger population from which they came.
the most genetic variation is i don't really care hoped it helps.. lol
Genetic drift is a product of random sampling. Like all forms of sampling or selection, variation within the sample set is required. Thus for genetic drift to occur genetic change (mutation) is required. However, it would be an error to call genetic drift a product of genetic change.
As you have less variety, eventually, people will have to breed with distant relations, therefore creating hereditary diseases.
