Study Notes
Selective Breeding
- Selective breeding transfers desired traits to future generations.
- An example involves breeding the fastest horse with the strongest horse to enhance overall performance in offspring.
Genetic Variation and Mutations
- High levels of genetic variation increase the likelihood of rare mutations occurring.
- Genetic diversity in a population facilitates adaptation and evolution through these mutations.
Inducing Mutations in Breeding
- Breeders can induce mutations intentionally to create variability.
- Common methods include the application of chemicals and exposure to radiation to alter genetic material.
Polyploidy
- Polyploidy refers to organisms possessing double or triple the normal number of chromosomes.
- This condition can lead to greater genetic variation and may enhance certain traits in plants and animals.
