In this episode of 'Bred to Perfection,' host Kenny Troiano and co-hosts Nancy and Frank Bradley deliver a hard-hitting critique of outcrossing in breeding, particularly within gamefowl. They argue that while outcrossing is often seen as a solution to genetic issues, it's actually a double-edged sword that undermines the very foundation of true breeding: the creation of a consistent, high-quality family or strain. The hosts emphasize that outcrossing leads to mongrelization, destroys polygenic traits, and introduces hidden deleterious genes that only surface generations later. They warn that hybrid vigor—often mistaken for permanent improvement—is temporary and not inheritable, making repeated outcrossing a cycle of short-term gains and long-term decline. The episode champions selective breeding, inbreeding for uniformity, and long-term programs like the Founders Program to build sustainable families. They also reflect on the decline of breed integrity, citing modern birds as increasingly muddied in type and health due to rampant crossbreeding and over-reliance on medication. The hosts stress that real progress comes from patience, discipline, and deep genetic understanding—not from chasing novelty or quick fixes.
Outcrossing destroys polygenic traits and undermines the consistency of a true breeding family.
Hybrid vigor is temporary and not inheritable; it cannot be passed to future generations.
Adding new blood to an established family resets progress and introduces hidden genetic defects.
True family development requires patience, selection, and inbreeding—not constant outcrossing.
A subline is a safer alternative to outcrossing, acting as an insurance policy for genetic experimentation.

The Mission of Bred to Perfection
Kenny Troiano opens the episode by reaffirming the podcast's mission to educate breeders with accurate, science-based information. He calls on listeners to rate, review, and share the show to help grow the community and spread truth in breeding.
The Myth of Outcrossing as a Fix
“You're not getting true hybrid vigor because of the mongrelization that's going on. You're getting a bump and because they get a bump, they think they're doing better.”
Hybrid Vigor: A One-Time Deal
“Hybrid vigor does make the offspring seem better than the parents. And in a lot of ways they are. But traits... when it comes to conformation... it's a matter of selecting for or selecting against it.”
The Dangers of Mongrelization
“We're not doing outcrossing. We're doing crossing. Crossing is worse than outcrossing. But we're not even doing crossing. We're doing, like I said, mongrelization.”
The Subline as a Safeguard
Instead of ruining a family with outcrossing, the hosts recommend creating a subline. This allows experimentation without damaging the main foundation, serving as an insurance policy if the new line fails.
