Which statement regarding evolution is false?
- Genetic drift due to a drastic reduction of population size is called the bottleneck effect. This type of genetic drift decreases the genetic diversity of a species.
- Sexual selection is a form of natural selection in which certain organisms will be selected over others based on certain traits.
- Disruptive selection occurs when a genotype is completely removed from a population, causing a drop in the genetic diversity of a population.
- Gene flow is another form of evolution alongside natural selection that results in the change of a population due to certain alleles moving in or out of a population.
