I used to ride this paint. He looked like a solid paint except for a perfect white blotch right in the middle of his tummy. No one ever knew he was a paint or saw the spot unless they were told it was there.
When a paint baby is born, it may or may not SHOW the color gene, but it will carry it (I believe), making it possible for it to produce a colored paint. I don't think people breeding for paints, necessarily hope for a solid paint (not that they would love it any less :) ), but they may end up with one. Even if it is born solid though, it is registered a paint because it has paint lines in either mom, dad, or both. That was as simply as I could put it...:)
Also, if you breed:
Paint w/color X paint w/color, you have 75% chance of paint baby
Homozygous paint X other horse solid or colored, you have 100%
Paint w/color X other breed (not paint) 50% chance of color
Paint w/color X solid paint, 75% color.......
.....I think that is the case, but someone can correct me if I am wrong...It may be a bit more complex. :)
Interesting post but I agree with what has been said. It would be the same thing with any other breed.
Actually I think paint is a dominant over solid so:
Paint x Paint (if neither is homozygous): 1/4 will be homozygous, 1/2 will be heterozygous, and 1/4 will be solid.
Paint x Solid (paint isn't homozygous): 1/2 will be heterozygous and 1/2 will be solid.
Solid x Solid: will always produce a solid.
Homozygous Paint x Heterozygous Paint: 1/2 homozygous and 1/2 heterozygous.
Homozygous Paint x Homozygous Paint: 100% homozygous paints
Homozygous Paint x solid: 100% heterozygous paints
^^A little bit of overkill on that one.
And imo, there is no "point" of solid paints, but they are classified as paints because of their breeding.
