Understanding Linebreeding: With Example of VA1 Zamp vom Thermodos and VA1 Jeck vom Noricum

 

The world sieger VA1 Zamp vom Thermodos was linebred (5 - 4) on the earlier the world sieger VA1 Jeck vom Noricum.

• What does these numbers (5 - 4) denotes?
• What is the possibility that Zamp will get certain traits transfused from Jeck? 
  

The numbers (5-4) in dog linebreeding refer to how many generations back a common ancestor appears in a dog’s family tree. In this case, Zamp vom Thermodos is linebred on Jeck vom Noricum, meaning:

• 5: Jeck shows up in the 5th generation on one side of Zamp's family tree.
• 4: Jeck appears in the 4th generation on the other side.

 

What Does 5-4 Linebreeding Mean?

Linebreeding is a strategy breeders use to enhance the genetic influence of a specific ancestor, in this case, Jeck vom Noricum. It’s a type of mild inbreeding meant to increase the chances that Zamp will inherit desirable traits from Jeck.

The closer the numbers, the more likely it is that the ancestor’s traits will show up in the offspring. A 5-4 linebreeding is moderate, meaning Jeck’s influence is noticeable but not as strong as if he appeared in closer generations (like 2-3 or 3-3 linebreeding).

 

Chances of Zamp Inheriting Traits from Jeck:

Because Jeck appears in both the 4th and 5th generations of Zamp’s lineage, there’s a moderate chance Zamp inherited traits from Jeck. However, since these generations are somewhat far back, the probability isn’t as high as if Jeck was closer in the family tree.

Several factors affect this:

• Coefficient of Inbreeding (COI): This measures how much genetic material Zamp might have inherited from Jeck. In this case, Jeck’s genetic contribution to Zamp is about 3.125%.
• Additive Effects: Traits are influenced by multiple genes, so even if Zamp inherited certain genes from Jeck, they may interact with genes from other ancestors and affect how the traits show up.
• Dominant vs. Recessive Traits: If Jeck had dominant traits, they would have a higher chance of being expressed in Zamp. Recessive traits would only show if Zamp inherited two copies of the gene.

 

Summary of Genetic Influence:

• Genetic Contribution: Jeck’s genetic contribution to Zamp is about 3.125%, due to the 5-4 linebreeding.
• Traits: Zamp has a moderate chance of inheriting traits from Jeck, especially in terms of conformation, temperament, health, and working ability, depending on what Jeck was known for.

 

Linebreeding like this is used to keep desirable traits in the bloodline while avoiding the risks of closer inbreeding, maintaining a balance of genetic influence from an important ancestor without losing too much diversity.
