Quick Summary

Linebreeding is a form of inbreeding where individuals are mated based on their relationship to a specific, superior ancestor. This practice aims to preserve desirable traits within a lineage. While it can concentrate beneficial characteristics, it often leads to reduced vigor, size, and fertility in offspring due to the increased likelihood of recessive harmful genes combining. A common method used in linebreeding is the backcross. This technique is employed in both plant and animal breeding to maintain specific genetic lines.1234
