FS | main characteristics | SOF | total |
FS1 | S20 originated from an aunt-nephew-mating with Fx = 0.0625 | 0.007 | < 0.01 |
FS3 | S20 originated from mating half-sibs with Fx = 0.125 | 0.014 | < 0.01 |
FS3a | based on the same structure as FS3, but it contained three inbred sires, Fx = 0.125 each, and offspring number of one sire (S20) in- creased to 138, while simultaneously reducing offspring number of GSS1 by 60 | 0.042 | < 0.01 |
FS3b | based on the same structure as FS3, but the offspring number of S20 increased to 138, while simultaneously reducing final off- spring number of GGS1 by 60 | 0.014 | < 0.01 |
FS4 | extension of FS3 by one additional strongly inbred sire from a full- sib mating, where one sib was already inbred, Fx = 0.375 | 0.056 | < 0.01 |
FS5 | contained two sires originating from a mother-son mating with Fx = 0.375, and a sire from a half sib mating Fx = 0.125, pedigrees of GGS1 and GGS2 remained fully separated from each other (this missing link was a remarkable deviation from all other FS) | 0.097 | < 0.01 |
FS88 | contains all sires inbred, Fx ranges from 0.063 to 0.375 | 0.150 | 0.01 |
FS99 | an extremely inbred design already starting with inbred grand sires, Fx of sires ranges from 0.250 to 0.426 | 0.290 | 0.28 |
