My stud is a minimal bay sabino. He is a clyde with a big blaze white lower lip two high whites on the hind legs and a "butterfly" on his belly. My mare is also a minimal sabino. Her base color is chestnut and she has the sooty gene. She has a big blaze, front socks and high white stockings on the hinds. She also has white speckles on her belly and around her udder.
So my question is what can this cross produce? Will I always get a sabino? What are the chances of the sooty gene being expressed? What about a maximum sabino? Is that possible from this combination?
Also for the stud - how often does the sabino gene pass down? Will it affect solid colored mares? How so?

Lori all purebreed Clydes & Shires are sabino so I would guess they pass it 100% of the time.
What breed is your mare? I have seen two minamally expressed sabinos produce maximal offspring.
What breed is your mare? There has not been much research of the sooty gene, but I would quess it would depend if she is homozygous or not.

Cathy ~ I did not know that all were sabino.
My mare is an anglo-arab. She is 5/8 arab out of and 3/8 TB/paint. She is a firecracker! The drop of paint only shows in color.

The sabino gene is linked with certain white marking patterns. I believe that in one of the recent post there is a link to the APHA color genetic site. It has a great description of the sabino gene and how it affects the color pattern.

Also there is a new foal who is a maximal sabino and his pictures can be seen in one of the posts here too. He is really interesting.

How often do you see maximal sabinos? It appears to be very rare. Is it associated with lethal white at all??

Lori crossing two sabinos always gives a greater chance of max. but I haven't seen it happen all that often.
There a a number of different genes in the sabino group. The test that UK does for sabino is for the gene that is common in TWHs. Clydes test neg. even though they all are.
Sabino is very common in the arab breed, but you don't see many max. arabs.
While sabino, splash, and frame are all grouped together under overo it is the frame gene that carries the lethal white gene.

The only testing done currently is for the Sabino 1 gene. That is the Sabino gene that can cause "Max White Sabinos". As someone already mentioned, Clydes test negative for that particular Sabino gene...so theoretically, it would be impossible to get a Max White Clydesdale.

yes I agree with Dona but one thing I think you will see in this cross is alot of roaning on the flanks and under belly white My mare this year was a minimal expressed sabino and she was bred to a tobiano, sabino expresses alot of roaning when two sabinos with belly white are bred together very common among clydsdales.
