I have a ( miniature) flaxen chestnut yearling , he hasnt been tested yet but I believe he carries splash and possibly frame ( his sire carries both), he is solid apart from a star ,a snip a small white coronet band and two white soles on his hind feet , he has one blue eye He was clipped a few days ago and on his body are around 8 or 9 spots , they are about an inch across , most of them are round in shape ,some of them angular , one of them goes up into the mane ...... are these spots caused by sabino ? at the moment the spots are on the skin but it looks like the the base of the hair could be turning white too sorry about he rubbish pic

Is the sire tested to carry Frame...they look like Sabino to me but, obvioulsy, if this is a breeding animal....

yes the sire is tested and he is positive , the colt will be tested, but if it cames back positive for sabino and frame that still wont tell me which caused the spots , does the shape ( ie angular versus round ) give any clue as to which pattern Im looking at or is there any other way to tell them apart
Im asking because Im trying to learn how to recognise eachl pattern

Now I'm not an expert on the sabino test, I'm pretty sure he'll test negative for it. To my understanding only maximal sabinos usually test positive for this test, but don't quote me on this!
A good way to identify sabino is 'haloing' around the edges of a white pattern. Like can be seen here around Tiger Lily's edges of her face markings.

Another good way is to look at the roaning that sabino creates (which of course is not classic roan) that can be most seen in the patterns of Tennessee Walkers.

It's still hard to tell them all apart most of the times, because they all like to clump together and "fight". Sabino is *really* a very general word that is covering our azzes from saying, "We don't know why that is happening, but we're going to theorize that it is sabino." We still don't know a whole bunch about the pattern and there are still alot of doors open for what it could/could not be. Heck, it could be multiple patterns that we just don't know about and we just clump them into one general term: sabino. This is why Nerd created this image:
:sabino
It's the sabino scape goat. :lol:

Do you mind sharing a whole picture of your colt? I'd like to see his other markings, just for curiosity. :)

The max sabino who tests positive for SB1 are homozygous for SB1.

Heres a good comparison for you

Sire who is SB1SB1

And his offspring who are SB1sb1

No, it won't help you tell and it is hardly relevant, anyway, so don't worry about it!!
Most Sabinos test negative for Sabino as only Sab1 can be tested, so he could easily test negative for "sabino" and still have Sabino.
Again, don't worry about it.
The only important one is the LWO test.

Would you state that all max sabino's are SB1? :?
That would make clydesdales another form of sabino, since they don't max out, to my knowledge?

Monsterpony Sun, 04/19/2009 - 10:21

No, not all max sabinos are SB1. Max sabino has tended to be a catch-all for a phenotypically all white horse. Multi-patterned (sabino + splash, sabino + tobiano + splash, etc), sabinos other than SB1 and dominant white have also been referred to as max white sabinos as well.

vneerland Sun, 04/19/2009 - 13:12

[quote="accphotography"]There are a few max white Clydes.[/quote]

:o

But since sabino is a breed trait, the occurence of Hmz sabino should be off the charts. It should be safe to assume that Clydes are primarily sabino [size=75]-insert number[/size]-instead of SB1. ;)

accphotography Sun, 04/19/2009 - 13:14

Or they're not max sabinos at all. ;) They're max splash, possibly boosted by sabino. :mrgreen:

[/quote]Nope.

I knew that sentence was going to be a bit confusing, but I wanted to keep it short and simple, that obviously failed LOL.

What I meant was if a horse is A.Max sabino AND B. Tests positive for SB1 he will be homozygous for SB1.

rabbitsfizz Mon, 04/20/2009 - 09:15

Are there....or are they the ones in NZ that are not , officially, "purebred"???
I am not knowledgeable enough on this breed to say one way or the other, but I do know they seem to test, as a breed, negative for Sab1, and yet they are, as a breed, H/Z for Sabino!!!
I cannot see any reason why Sabino cannot go maximum without Sab1.....
In fact I had not heard the theory that [i]all[/i]max Sabinos are Sab1?????

Songcatcher Sat, 05/02/2009 - 10:54

I'm relatively sure that not all max Sabinos are SB1, but if my understanding is correct from the article I read on the woman who developed the SB1 test, all homozygous SB1s are Max.
