Question

Genetic drift tends to occur in populations that (1 point)are very large. are small. are formed from new species. have unchanging allele frequencies

Answer 1

The answer is that are small

Biologists consider genetic drift as a random change in a gene variant due to random sampling organism

Answer 2

Answer: The correct answer is-

Genetic drift tends to occur in populations that are small.

Genetic drift can be described as an evolutionary mechanism, according to which frequency of gene variant ( that is allele frequency) changes over generation within a population due to some random/ chance events.

It has a pronounced impact on population with small size.

This is because in small population, infrequently-occurring gene variants have a larger probability of getting lost.

As it is initiated,it will continue until the gene variant is either lost or is the only allele left at the gene locus within a population.

This will result in the decrease of the genetic diversity of population.
