Which mating system introduces unrelated animals from another population to increase genetic variation?
Correct answer: B. Outcrossing
- A. Close breeding
- B. Outcrossing
- C. Self-fertilisation
- D. Linebreeding
Explanation
Outcrossing involves mating animals that are not closely related, often within the same breed, and helps maintain genetic variation. Linebreeding and close breeding increase relatedness instead.
