True breeding refer to an organism that always passed a certain genetic to its offspring.
Some advantages of true breedings are :
- Diminish the probability of Genetic Mutation
- Reduce the risk of Genetic Extinction
- If used in industry, it could be used to produce/bred the exact type of products
