Is gene flow the same as genetic drift?
Gene flow is the process of alleles going from one population to another, while genetic drift is the alteration of allele frequency in a gene pool.
How do genetic drift and gene flow differ in their respective outcomes?
Gene flow occurs by the process of interbreeding or inbreeding through migration with the adjacent population. While the genetic drift occurs by the process of sudden eliminations or sampling error for a gene or allele in smaller populations.
Is genetic drift the opposite of gene flow?
The main difference between gene flow and genetic drift is that gene flow refers to the transfer of genes between populations whereas genetic drift is the variation of allele frequencies in small populations, allowing the disappearance of alleles from the population.
How does gene flow differ from genetic drift quizlet?
Gene flow differs from genetic drift because it is the: Spread of new genetic material from one gene pool to another.
What is required for gene flow but not genetic drift?
Gene flow differs from genetic drift because it is the transfer of alleles or gametes from one population to another. It happens when a population migrates or becomes geographically isolated.
What is an example of gene flow?
If a bee carries pollen from one variety of squash or cucumber to another (within the same species), that will result in hybridization. If you save seeds from a squash or cucumber plant and the resulting fruit does not look like the fruit from the original plant, that is the result of gene flow.
What is the difference between genetic drift and natural selection quizlet?
Genetic drift causes evolution by random chance due to sampling error, whereas natural selection causes evolution on the basis of fitness.
What are some of the key differences between natural selection gene flow genetic drift?
Natural selection is like genetic drift but with one major difference—it’s not random. And unlike genetic drift which can be helpful, detrimental, or have no effect, natural selection represents only positive change/adaptation.
What genetic drift means?
Genetic drift is a mechanism of evolution characterized by random fluctuations in the frequency of a particular version of a gene (allele) in a population.
What is an example of genetic drift?
Genetic Drift Example Consider a population of rabbits with brown fur and white fur, white fur being the dominant allele. Due to genetic drift, only the brown population might remain, with all the white ones eliminated. A couple with brown and blue eyes have children with brown or blue eyes.
