What is genetic drift?
Q: What is genetic drift?
A: Genetic drift is a random effect on biological populations which reduces the amount of genetic variation in the population.
Q: What are some forces that add heritable variation to a population?
A: Mutation and recombination are two forces which add heritable variation to a population.
Q: Are there any factors that remove variation from a population?
A: Yes, genetic drift is one factor which removes variation from a population.
Q: How does genetic drift reduce the amount of genetic variation in a population?
A: Genetic drift reduces the amount of genetic variation in a population by randomly removing certain alleles or gene variants from the gene pool over time.
Q: Is mutation an example of something that adds heritable variation to a population?
A: Yes, mutation is an example of something that adds heritable variation to a population.
Q: What other force can add heritable variations to populations besides mutation and recombination?
A: There are no other known forces besides mutation and recombination which can add heritable variations to populations.
