LINE BREEDING

The linebreeding charts available on each hypothetical mating report give you the ability to quickly analyze a mating out to 9 generations. An example of the linebreeding report for the hypothetical foal of Cryptoclearance & Spain is shown below. From the linebreeding chart, we can see that Mr. Prospector shows up in the pedigree 3S x 4D. That means that he appears in the third generation on the sire's side of the pedigree and in the 4th generation on the dam's side of the pedigree. The upper case 'S' also lets you know that the inbreeding is occuring through a son of Mr. Prospector. Crosses through daughters would show up with a lower case 's' or 'd'.

The number of crosses or times that the ancestor appears in the pedigree shows up next. In Mr. Prospector's case, there's are only two occurances or crosses in the 9 generation pedigree.

The number of lines tells you how many different sons/daughters of Mr. Prospector are represented. In this case, there are two lines, one through Fappiano, and the other through Gulch. The lines are then broken down into male & female lines.

The blood % field let's you know how much of the blood the ancestor contributes. As an example, the parents of any horse contribute 50% of the blood. A grandparent contributes 25% of the blood. Mr. Prospector is contributing 18.75% of the blood in the mating between Cryptoclearance/Spain.

The influence field lets you know what the inbreeding is equivalent to in simple terms. So, when you see a link like Nearco: 7S x 8D x 7D x 8d x 8D x 6d x 9D x 8D x 9D", the influence field will boil that down and tell you that the inbreeding is equivalent to a 5x6 inbreeding to Nearco.
