Shetland Sheepdog ROM Inbreeding coefficients

This table gives the inbreeding coefficients (COI) calculated from the foundation stock by Dr. Armstrong for each of the ROM Shelties (except the most recent.) Note that some assumptions behind this calculation were:

  1. Chestnut Sweet Lady was a Collie, rather than a full sister of her mate's dam, Chestnut Lassie. This probably decreases the inbreeding substantially below what it would be if the paper pedigree was used.
  2. Jean of Anahassitt kept her Sheltie pedigree, even though she is thought in reality to be a Collie cross. This artificially increases the inbreeding on Ch Mowgli and his descendants.
  3. Ch Kim o'Page's Hill is kept with Ch Mowgli as his sire, even though in reality he is thought to have been sired by a Collie. This again artificially increases the apparent inbreeding down the line, expecially in descendants such as Ch Musket o'Page's Hill.
  4. All other foundation dogs were assumed to be unrelated to each other. (The ROMs as a whole trace to just 160 foundation dogs and bitches.)

In general, the early inbreeding coefficients tend to be higher for Page's Hill and derived kennels, and relatively low for Pocono. How much of the high values for Page's Hill are due to the use of official pedigrees for Ch Mowgli and Ch Kim o'Page's Hill is uncertain at the present. Note that an inbreeding coefficient of 25% is what would be produced by a full brother-sister mating if the grandsire and granddam were completely unrelated. The ROMs are given in birtdate order.
