New to this - lots of questions

[lotsofquestions]

Please know that I enjoy your message board very much.
I have questions that I will post and hope that I can be led in the right direction:
Where do I find the latest definitive information on the genetics of sabino; specifically I would like to know if a gene for sabino has been found. Also, has a direct genetic corelation been established between sabino and overo, and where I would find this information. Am I right in assuming that sabino is an inherited trait? Is there no specific way to establish whether an animal with sabino markings will throw those markings or not, or how far into the future the sabino characteristics will carry, or back in the past an animal inherited those traits? Is there any information on where this coloration came from? Can the coloration (inherited gene?) ever be wiped out by trying to breed only solid colored animals (with one sabino ancestor or more); or is there always a chance to produce a loudly colored animal forever and ever?
I am sorry if I sound totally stupid on this issue, but the fact is I am. All help and information is appreciated.

Just wanted to say welcome and sorry but most of your message was wy over my head - I haven't a clue! Hope you get your answers soon.

There is a test for the sabino gene available in the US.

"Sabino
Sabino is a Paint color pattern that is variably expressed and can range from white stockings and a blaze to white leg and face markings and extensive white spreading up from the belly into the body area. The mutation we detect is indicative of the Sabino1 gene. Homozygous sabinos may have more extensive white than heterozygous horses. There is more than one sabino gene so that a horse that appears to have the sabino pattern may test negative for the Sabino1 gene. So far all horses that test positive for Sabino1 have the sabino pattern."

Journal with article on dominant white that mentions sabino:
