Inbreeding

Inbreeding is the term utilized to describe breeding in which the same ancestor appears two or more times within the first four generations of pedigree. For example, if the same ancestor appears in the third generation and again in the fourth, the horse is referred to as being "inbred 3x4." The significance of inbreeding is that the ancestor to whom the particular horse is inbred will have greater influence, thus emphasizing certain characteristics. Most believe it is radical for a horse to be inbred closer than 3x3.
