The Genetics Of Anhidrosis

Anhidrosis the complete or partial inability to sweat occurs more frequently in some breeds and among horses with a family history of the condition which suggests a heritable component.
Question Can a horse inherit a susceptibility to anhidrosis? Im considering breeding my 9yearold Quarter Horse mare who is lovely in every respect but has a very limited capacity to sweat. She was actually relocated up here from down south because living in a hot climate was intolerable and unsafe for her.

My mare sweats a bit now but not nearly close to normal. Even though our summers here are fairly temperate I have to keep a close eye on her. I dont ride her when the temperature is above 80 degrees or its humid. She is otherwise healthy has great gaits and is highly trainable so I would love to have a foal from her. But I dont want to breed another horse that cant sweat normally.
If anhidrosis can be inherited would selecting a stallion who doesnt have the problem cancel out my mares DNA contribution?
Answer I am so pleased you asked this question as its clear you are thinking hard about whether all your mares traits are worth passing on to the next generation instead of just focusing on the good ones. Anhidrosis has a substantial impact on affected horses so it really is a welfare concern that is to be avoided as much as possible.
