Question
Which process increases genetic variation in a population
Answers
GPT-4o mini
Genetic variation in a population can be increased through several processes, including:
1. **Mutation**: Random changes in the DNA sequence can create new alleles, introducing new genetic material into a population.
2. **Gene Flow (Migration)**: The movement of individuals and their genetic material between populations can introduce new alleles to a population, increasing its genetic diversity.
3. **Sexual Reproduction**: The recombination of genes during the formation of gametes (through processes such as independent assortment and crossing over during meiosis) can create new combinations of alleles in offspring.
4. **Outbreeding**: Breeding between individuals from different populations can create hybrids, leading to novel genetic combinations and increased variation.
Each of these processes plays a crucial role in shaping the genetic landscape of populations over time.
