Respuesta :
Genetic drift is the generational shift in allele frequencies in a population that results from random events. Genetic drift is actually a change brought on by "sampling error" while choosing the alleles for the following generation from the gene pool of the current generation.
Which phrase best expresses genetic drift?
A method of evolution known as genetic drift occurs when a population's allele frequencies shift over successive generations owing to randomness (sampling error). All populations of limited size experience genetic drift, but its effects are most pronounced in small groups.
What are some examples of genetic drift?
Think of a population of rabbits having brown and white fur, with the dominant gene being white fur. Genetic drift may result in the eradication of the whole white population, leaving only the brown population. Children of a brown-eyed pair and a blue-eyed couple have either brown or blue eyes.
Who first suggested genetic drift?
The shifting-balance theory of evolution, developed by Sewall Wright, is based on genetic drift.
