Question
Which mechanism(s) is/are the source of variation within a population?
Answers
GPT 3.5
1. Mutation: Changes in the genetic material of an organism can lead to variations in traits within a population.
2. Genetic recombination: During sexual reproduction, genetic material from two individuals combines, leading to new combinations of genes and potential variations in traits.
3. Gene flow: Movement of individuals between populations can introduce new genetic variations to a population.
4. Genetic drift: Random changes in gene frequencies within a population, particularly in small populations, can lead to variations in traits.
5. Natural selection: Differential survival and reproduction of individuals with certain traits can lead to changes in the frequency of those traits within a population, resulting in variations.
