Questions and Answers
What is the main assumption made when modeling changes in allele frequency in a very large population?
That the population has a very large number of individuals and therefore randomness does not matter.
What is the result of stochasticity in a small population?
Random deviations in contributions between genotypes, leading to changes in allele frequency.
What is the term for stochastic changes in allele frequencies?
Genetic drift.
