FAQ
Frequently Asked Questions
Line breeding is a specific, less intensive form of inbreeding. It involves mating related animals, but typically avoids the closest possible relationships (like parent-offspring or full siblings), aiming to balance trait preservation with manageable genetic risk.
The main risks are a reduction in genetic diversity, which can lead to inbreeding depression (reduced fertility, vitality, and health), and an increased chance of harmful recessive traits becoming expressed.
It is commonly used in the development and maintenance of pedigree dogs, livestock (cattle, sheep, pigs), horses (especially racehorses and show horses), and laboratory animal strains.
Line breeding works within a closed or related genetic group to reinforce traits, while crossbreeding mates animals from distinctly different breeds or lines to combine traits or introduce hybrid vigour (heterosis).
A controlled breeding method where animals are mated within a specific family line to concentrate desirable traits.
Line breeding is usually technical / scientific in register.
