5 Questions
Which of the following mechanisms of evolution does not lead to adaptations?
Genetic drift
What is genetic drift?
A random change in allele frequencies from generation to generation
How does genetic drift affect small populations?
It decreases allele frequencies
What happens to allele frequencies in genetic drift?
They fluctuate randomly
Which of the following scenarios is most likely to result in genetic drift?
A small population with low mutation rate
Learn about the non-adaptive mechanisms of evolution, including genetic drift, migration, mutation, and nonrandom mating, and their impact on allele and genotype frequencies. Explore how these mechanisms contribute to evolutionary change alongside natural selection.
