Pedigree Query

My understanding of the dun vs buckskin is that it depended on the breed and also era.

The advent of genetics as a science turned the whole color thing upside down. What folks are finding is that the phenotype color doesn't always look like the expected genotype.

Checked both cases with other non-Del Mar sources and both are officially registered as (so-called) "Duns". Up to 1968 these were the only two "Duns" appearing in "Sires of American Thoroughbreds". I doubt there were other cases inscribed after 1968, yet who knows!

Ty Time's broodmare sire, Barney Lucas, has been the subject of other threads among dilute coat color enthusiasts here, but I don't have at hand the reference. Perhaps doing some "search" will help.

Any idea on how to prospectively calculate the probabilities of achieving a mainstream competitive appaloosa Thoroughbred coming from a non-Thoroughbred lineage. Many thinking caps and opinions are needed here!
Please post your opinions.

Interesting page and new avenues of search.

This very interesting stallion lives in Angrovestud's country. Take a look!

LP or PATN just haven't shown ANY signs of being in the TB gene pool, ever. So unless you could take a current colored highest percentage possible TB Appaloosa and get it registered with the JC there is just no way to introduce the pattern to registered TBs now.

It was the 80s before people finally realized that dun and cream were different genes. In the UK and Europe many breeds/people still use "dun" for cream. I'm guessing those lines probably died out though.

you would also have to have your breeding programme perhaps in the UK were you could add the gene at foundation level and then send youngstock over in a few generations it would be a very long term project as I know we are doing this with the Tobiano gene.

Jorge, Please explain here. You are looking for a TB that looks Appalooosa, but not have any TB bloodlines?

There are a fair few 7/8th tbxappaloosas around.and the majority are, strangely enough, coloured.
however, even though they are 7/8ths tb, would they still only be first generation (of 8?) doing the project like angrove?

and.. do you have to live in UK to register with UK studbook?

I still hear quite a few people calling duns buckskin and vice versa. And I still see duns gettting registered as buckskins. This is a dun paint gelding I use to own.You can see he is a buckskin color, but he has dun factor. [img][img]http://i104.photobucket.com/albums/m171/arcticcielo/buckandme.jpg[/img][/img]

I'd have called him grullo.

right, because of his dark face

He was registered as a dun, but in the beginning of summer his whole body would be grullo, then sunbleach(?) to the "buckskin" color and stay that way all winter. I would also say grullo, just making a point that he has the dun factor but most everyone called him a buckskin.
