Genetic Analysis of the Breeding

Chuck Felones × Banea Difesa

A carefully planned pairing, based on an in-depth study of bloodlines and on the principles of population genetics applied to the selection of the working German Shepherd.
The goal: to consolidate functional traits without compromising genetic diversity or health.

📊 Genetic Data (10 Generations)

• Inbreeding Coefficient (COI): 1.73%

• Ancestor-Loss Coefficient (AVK): 46.77%

These values demonstrate an optimal genetic balance: minimal inbreeding risk, combined with a solid genealogical structure where selected ancestors are repeated deliberately.
The result is a controlled technical outcross, designed to preserve genetic stability within the working type.

🧩 Bloodlines and Key Ancestors

The pedigree includes many of the most influential ancestors in the modern working German Shepherd heritage:

• 🧠 Fero vom Zeuterner Himmelreich – mental strength and steadiness;

• ⚡ Yoschy von der Döllenwiese – intensity, drive, and strong prey instinct;

• 💪 Troll von der bösen Nachbarschaft – concentration and controlled hardness;

• 🧭 Asko von der Lutter – mental balance and clarity;

• 🔥 Fado / Haska / Roma von Karthago – functional structure and working drive;

• 🛡️ Orry von Haus Antverpa – operational courage and emotional stability.

These bloodlines — Karthago, Antverpa, Döllenwiese, Zeuterner Himmelreich — form a genetic backbone that combines endurance, character, and functional morphology.

⚖️ Academic Interpretation

This breeding lies within the ideal zone between heterosis and consolidation:

• The low COI (1.73%) ensures wide allelic diversity and reproductive health.

• The medium AVK (46.77%) guarantees stable transmission of temperament and functional traits.

It’s a combination that unites vitality, behavioral predictability, and structural consistency, avoiding both inbreeding and excessive genetic dispersion.

🐾 Expected Progeny

Puppies from Chuck Felones × Banea Difesa are expected to show:

• Strong nerves and excellent recovery after stress;

• Balanced yet determined temperament;

• High trainability and working focus;

• Mental and physical resilience;

• Pure working morphology, dark pigmentation and solid structure.

💥 Perfect for IGP, Mondioring, obedience, and operational or service work, yet equally suited for active family life when raised in stimulating environments.

🧠 Conclusion

The breeding Chuck Felones × Banea Difesa stands as a model of functional selection, combining genetic rigor, health, and temperament.
It perfectly aligns with modern population genetics principles — producing dogs that are sound, stable, and true to the essence of the working German Shepherd.

Some litters are legend.
