DDR - Page 1

I owner of Cyrus von der haus Gill, what % of DDR is he if anyone know. thanks

Very nice boy!

Percentage doesn't work quite like that. You can cross DDR with a Showline. The progeny would be half-show, half-DDR; but genetically they are not 50/50 as some traits can be more strongly inherited from one parent, or the other. His lineage can be predominantly one line or the other, but it does not mean he is genetically a specific amount.

I cringe when breeders claim their dogs are x% DDR, and it's something like 78% or 99%. The actual amount can't be calculated like that. (Same thing with wolfdog breeders who claim exact percentage of real wolf on their wolfdogs. Different content percentage can exist within the same litter.) Anyhow, nice looking dog, and he has some individuals in his bloodlines I have always been partial to.

Only phenotypes can vary, not percentages.  They ARE genetically 50/50, with exception of the sex chromosome and environmental influences for epigenetic change.  The genotype percentages are true as they get, by way of independant assortment.  Phenotype expression can vary, yes, but whatever's "dominant" doesn't affect the percentages of contribution in the following generation, either.

I'm one of those breeders, that claims one of my dogs comes from 75% old east german bloodlines, because SHE IS.  There's nothing inaccurate about stating it, nothing to be proud about, it just is what it is.  Only forces like evolution, that cause mutations like transcription errors and tandem repeats can take away what your ancestors have given to you.

To answer the original poster's actual question, 7 out of the 8 dogs in the 3rd generation are from the DDR or both their parents were from the DDR.

New here so please be gentle.

DDR this, Czech that, or WG this....I think is irrelevant. The dog is a German Shepherd.  If you look back at this dogs ancestry they are all WG bred...well most of them. I think what is more relevant would be to say was the dog bred or were the parents and its ancestry bred from a program incorporating a specifically designed DDR breeding program (with the outcome to meet certain specific goals of that program).  Then to me that would makes a bit more sense. 

Just my thoughts!

With wolfdogs, anything beyond the first cross 50/50, you can't be certain of how many wolf genes they inherited.  This gets even more uncertain when crossing wolfdogs with wolfdogs.  The same would go for designer breeds, and even for lines if you are trying to say how much of their actual genes reflect their heritage.  

Using the wolfdog example: a pup is born from a full dog and a first gen. half wolf.  The half wolf can theroetically pass on all the wolf genes, making a pup 50/50 in genotype too, or pass on all dog genes making the new one full dog in genotype and phenotype, either result would be extreme but theoretically possible.  Statistically though the litter is likely to show a bell curve with most around 75% dog and 25% wolf in geneotype.  

Regardless of what their geneotype is you can still accurately say that their pedigree is 25% wolf, but it doesn't necessary mean that individual is in genotype.  Likewise, if you chose to you can say your dog has a pedigree made up of XX% DDR bloodlines.  Personally I prefer to use the terms "full", "most", "half", and "some" as percents do not reflect genetype and if you look closely (even at those "100%" pedigrees) you can often find other lines, or grey areas.

Good luck with your dog!

You can't be certain, because of the multifactoral traits involved expressing their characteristics, but you CAN be certain in the amount of genetic material, which is consistently halved.

From a reverse perspective, even "100% DDR" dogs don't have all the characteristics typically associated with them.  Such as not having large bone and blocky head type, for example.
