What is Paint Horse?

Breeding Stock Paint:  One or both parents have color but the resulting foal has no color (breeding stock).

Heterozygous Tobiano:  This horse has tobiano color and carries one tobiano gene (T) and one non-tobiano gene (t).

Homozygous Tobiano:  This horse has tobiano color and carries two copies of the tobiano gene (TT).  This horse will be a 100% producer of tobiano babies.

Lethal White:  An all white foal born with an improperly developed digestive system.  The foal will colic and die several hours after birth.  A lethal white foal can be a result of breeding overo horses, most commonly overo to overo or overo to solid.

Non-Tobiano:  Term used in genetic testing and blood typing referring to any horse that does not carry the tobiano gene (i.e. overo, breeding stock, quarter horse, Arabian, etc.)

Overo:  Color pattern found on paint horses - no white crosses the spine, the face is often mostly white, and legs are often dark.  "Glass" eyes are also common.  The variations include:  small white spot on the belly with no other white, mostly white with a wide, dark strip down its back.

Tobiano:  Color pattern where white will cross the horses spine.  The legs are often white and the head is often dark with a star or strip.  There are also many variations with this pattern:  minimal white (legs are white and a couple spots on the body with one crossing the spine) to excessive white (horse is mostly white except for a few scattered dark spots.)

Tovero:  This horse has both tobiano and overo markings.  He will have a mostly white head extending up from muzzle, dark ears, dark coming from chest and flank, dark around the tail head.
