100% if you buy one, no telling if you breed.
Best answer here!
If you want a specific color and gender then buy a foal. Then you are guaranteed to get the color and gender you want.
Just to point out you don't nead to know about colours and genetics to be able to look after a foal.
No, I suppose you do not need to. But there is this little thing called being responsible. Why would someone who does not even know the most basics about horse colors be trying to breed their horse? Even more so, why would they be trying to breed their horse for a specific color?
Just like everything else, anyone can reproduce (humans, dogs, cats, etc), not everyone should though.
The mare:She is a full paint, brown body. Her mane&tail is color based blond and red in it. (I have a photo of her in my profile).
Serious question, did you post this to be silly or do you truly not know what color your mare is?
I looked at the photo and brown is not the word I would pick for your mare.
Unless the photo is bad she looks very chestnut/sorrel to me.
