Hello I have a Question about Inbreeding.

As far as I know inbreeding occours, when you breed two Pets which are related within 3 Generations:

0: Sibling/Cousin

1: Parent, Uncle/Aunt/ Cousins

2: Grandparents/Granduncle/aunt/ Cousins

3: GreatGrandparents/Greatuncle/aunt/Cousins- (I am not sure if those count as well)

An example to clarify my question.

I have two pets and I breed the Child of one pet with the Child of the halfbrother of a pet. Is "Half"Sibling inored or not?

PetA     HalfbrotherPetA

ChildPetA    breed with Child of Halfbrother (Cousin to a half)

Result: Full Inbreed?

Normaly I would say that this would be an inbreeding. 

But I am not sure If such "Half-Relatives" have a less harsh effect at the breeding. Most Pets have half Siblings as far as I can see, So it would take a huge amount of research and notes to ensure clean family lines (without premium account naturaly)

I just want to know if this research is nessecary or not ;)

Thanks for any help

(sorry for my bad English, I am not a native speaker, but I am happy if you point out grammatical errors)

So... trying to sort things out in my head.

Newborn

child/parent X child/parenthalf

grandparent1 X grandparents2      grandparent1 X grandparent3

If I got the scenario pieced together correctly, then yes, the baby would have a pet show up twice within three generations, and as such it should result in degeneration.

Now, degen is what it is, a set penalty, no scale of severity, but it can both be countered in the pet itself (good genes, ensuring GP), as well as be bred out again for future generations.

Thank you very much tha answers my question. :)
