An important question is just how much can a stallion influence the outcome of any given match? Modern genetic studies bring to light just how important the mare line is due to the transmission of the X chromosome. The stallion can only pass on one X chromosomewhich comes from his dam to his fillies and none to his colts while the mare passes on one of her X chromosomes to every foal. Our conclusion is that the mare in a pedigree is of equal importance to the stallion.
Watchman looks at genetic potential in three places: the sire line, the sire's dam line, and the mare's dam line. The Y chromosome always comes from the sire; the X chromosome(s) comes from the sire's dam and/or the dam depending on the sex of the foal.
