What's happening at the F1 & F2 level in WM Farms Breed Preservation?
Breed preservation is a multi-generational process. You cannot undo a breed-wide bottleneck or rescue an endangered bloodline in a single generation. When breeders talk about an "outcross," they often expect immediate results. In reality, the first cross is just the foundation. At present we have 8 F1 crosses from different geographical regions and kinships.
The Generational Breakdown:
F1 (First Generation): Injecting Diversity
The Goal: Bring in completely new, unrelated genetics to break up severe inbreeding.
The Reality: This generation is or has been the most unpredictable. We are combining two very different genetic maps. The puppies will be highly heterozygous (genetically diverse), but they will look and perform with a higher degree of variation. We understand that we may lose a little "breed type" or specific traits we are trying to preserve. However, it works both ways. Pepper and Cora, both F1 US x UK crosses both retained a very high level of working drive, prey drive while retraining an incredible biddable attitude. working very much in our favor. I believe this is due to our pairings and understanding the base field nature of the goldens we are breeding.
F2 (Second Generation):
Managing the Split
The Goal: Breed an F1 back to the original breed line (a backcross) or to another carefully selected outcross. (Subpopulation)
The Reality: This is the hardest stage. Mendel's laws of inheritance peak here, meaning the genetics "segregate." Some puppies will heavily resemble the outcross, some will look exactly like the original breed, and some will be in the middle. At this level, we must select which puppies retained the new genetic diversity and the essential breed traits.
F3 (Third Generation): Consolidating the Type
The Goal: Establish uniformity while keeping the new genetic health benefits.
The Reality: By the third generation, we begin to lock in the "breed type" again. The dogs look, move, and act like the goal, but their internal genomic architecture is vastly healthier than the bottlenecked population we started with.
Why our Metrics of (IR 0.0 / Gen Dist 0.50) fit this process at the beginning stages.
If you are doing preservation work, a genetic distance of 0.50 and relatedness of 0.00 might represent a crucial F2 or F3 stepping stone. If you start with a massive F1 outcross (e.g., Genetic Distance of 0.70), you cannot stay there forever, or you lose the breed entirely. You must eventually breed back toward the population baseline. A pairing that lands at a stable 0.50 allows us to "hold the line" it keeps the inbreeding low while you work on stabilizing the physical traits, temperament, and health clearances of our preservation project.
Managing seven simultaneous lines at one time fits well into our 15 year plans for this level of preservation work. It allows us to run F1-to-F3 generations in parallel, giving us the critical freedom to outcross one line while keeping another stable, and eventually weaving them back together without bottlenecking our self. When juggling seven distinct lines, a pairing with a 0.0 relatedness and 0.50 genetic distance serves a very specific, tactical purpose in our master grid.
Because these numbers hit right at the breed baseline, these F1 or F2 pairings will maintain or act as a "diversity injector" line at some point.
Using 50-year-old frozen semen is a monumental, one-shot opportunity for our preservation project. This semen represents a genetic time capsule from 1975, it may possesses ancestral alleles that have likely been entirely lost or heavily diluted in the modern gene pool.
Splitting this rare genetic resource across two vastly different sub-populations, a UK working golden and a US field golden is a calculated preservation move. In the global golden retriever gene pool, the UK lines and the US field lines represent two of the most genetically distinct, geographically separated sub-populations within the breed. By dropping 1975 genetics into both, we are essentially launching two completely independent preservation tracks within our 7-line matrix.
By keeping our other 5 lines running simultaneously, we can use them as customized "landing pads" for the next generations. For example, down the road, we can take a high-diversity puppy from the UK track and breed it to a highly stabilized F2/F3 golden from our field lines to instantly lock down the field breed type while locking in that priceless 1975 DNA.
The final blueprint
Integrating 1975 conformation genetics, a DDHF, ***, agility, gundog and an AFC across seven parallel lines to engineer the ultimate, highly functional field golden is our ultimate goal. We are executing a classic convergent breeding matrix. By taking highly divergent inputs, refining them in isolation, and weaving them back into a single, unified, genetically superior working golden.
The goal is to end up with a highly functional field golden, one with elite working drive, athletic endurance, much improved health, and the structural soundness and athleticism to the field demands. Our lines will converge systematically from F1 (divergence) to F4 (unification).
