White faced horses?

Ok, got a new boarder in our barn who has a sorrell paint with a medicine hat, two blue eyes, big spots on both flanks, one on her shoulder and her mane and tail have two different colors in them. I would post a pic but I don't have one and not sure she would allow me to.

She wants to breed her but not to another paint because her mare has had cancer in one eye (the one without the liner) to a bay lusitano, I think.

My question is, her mare can still pass those genes on that put white on the face but what's the likelyhood it will happen with the solid bay lusitano? I am just curious and want to help her if I can. I do not know if she has had her gene tested or not but wanna talk to her about it next time I see her.

Hmm, I do not know a lot about genetics when it comes to colouring. However, I do understand that generally, cancer can become a hereditary disease, generally if one parent has had it (anywhere) the offspring is at a greater risk of it. If I knew a broodmare had had cancer (anywhere) I would generally be put off the offspring. But that's just me.

Agree completely. I wouldn't breed a horse that has had Cancer, but that is me.

I also agree but it's not my horse and I want to help her. Any thoughts on the originsl question?

I personally would persuade her form breeding that cross. Not only will it either be REALLY good, or REALLY bad, there are already plenty of paint cross horses out there, especially with the overpopulation we already have in the US with horses.

It's not uncommon for horses with white faces who lack natural "eyeliner" to develop skin cancer from the sun in those eyes. Many people have eyeliner tattooed on to prevent the sun from damaging the sensitive skin surrounding the eye.

But to answer your actual question: yes, she can pass on those genes. Bald faces and blue eyes are both caused by frame and/or splash. If she's frame, she's heterozygous for it (this gene in its homozygous form is lethal and the mare wouldn't have made it past a few days of life), meaning she will pass it on 50% of the time. Same with splash, if she has it. I couldn't tell you automatically if she is heterozygous or homozygous, but there is still the possibility of it being passed on.

I would just like to know what the owner of the mare is trying to achieve from this cross . . . If color is the only motive that's completely irresponsible.

Thanks poseidon, I really appreciate the information!

I could be wrong on the lusitano part and as for use, I do not know, she is a new boarder at our barn.

Add in based on her description Po, it sounds like she might be carrying tobiano as well...
