i don't know, but it seems like most standardbred horses are bay.
You see so many bay horses because the bay color gene is dominant. In most cases it can over-ride black and it varieties and even grey and its varieties. When breeding a chestnut with a bay it's about 50-50 whether you will get chestnut or bay.
Chestnut is a color and not a breed. Most breeds of horse come in chestnut along with many other colors. So yes Chestnut horses can come from America, but they also come from everywhere else.
In horses liver chestnut is a type of chestnut. So chestnut to chestnut will produce a chestnut foal. The actual shade of chestnut will be controlled by underlying factors that are not well understood.
Chestnut is a color, and color ahs nothing to do with age. So a chestnut horse can be any age.
The only true color genes are black (E), which is dominant, and red (e) which is recessive. Dilution genes create a majority of the other colors: Cream (Cr) is incomplete dominant -- Palominos, Buckskins, Cremellos Dun (D) is dominant Champagne (Ch) is dominant Silver (Z) is dominant Roan (R) is dominant
They are different colours, such as black, brown, chestnut, white and so on.
I just wanted to add information about equine color genetics so you can better understand horse color. Horses have two base colors, Black and Red. Black is represented by an E which is dominate and Red is represented by an e which is recessive.A black friesian can have 1 of 2 pairs, either EE (two black genes) or Ee (a black and red gene). If you breed two horses together that bother have Ee, you can get EE Ee or ee. So you'll have a 25% of black coat with only black gene, 50% of black coat but carries the red gene, and 25% of a chestnut coat that doesn't carry any black.>>E eE EE Eee Ee eeAnd Yes because a friesian has a black base they can also come in Bay, which attaches itself to the E gene. As far as I know Black is the only coat color that is accepted by the registry so that's what breeders breed for.--A chestnut Friesian may be produced if both parents carry the chestnut gene, but it is rare. These horses sometimes go by the name "fox or foxy friesian." Before the 20th century, Friesians used to be all colours but over the years, the registry chose to select for only black coats. The chestnut gene is recessive, meaning it gets carried along with the dominant black gene, but only shows up every once in a while, when both parents carry the chestnut gene and the odds turn out right. However, the Dutch registry the KFPS continues to select only for black coats, so chestnut foals are not usually eligible for full registration and breeding privileges within the registry.--If you are talking about the breed Friesian in real-life, then no. The friesian can only be black, or else it it not considered a friesian. I suppose if for some reason, both parents carried the albino gene, the friesian would be albino but that is extremely unlikely.--ACTUALLY the above statement is FALSE. A Friesian in REAL-LIFE can also be BAY. Or even grey but they are not accepted in the FHANA.--I would like to know what in the first statement make this false information. The question was in regard to a Chestnut Fresian, not bay or grey... Please clarify. Thank you!---To the third answer - albinism simply does not exist in horses. Dominant White and OLWS (Overo Lethal White Syndrome) horses are the closest you'll get, which do not exist in Friesians.Also to get back on topic, chestnut does occur in Friesians. They are accepted in the FHANA rarely but their offspring cannot be registered.

You could get either a palomino or a chestnut. Since a palomino is a diluted chestnut, and a chestnut has no dilution genes, it will balance out the foal's genes so that it could be either color! Good Luck!
Because you can catch horses! --EmeraldLemon-- (Chestnut) http://www.freewebs.com/guideofhorseisle/index.htm
It depends on the other genetics that help determine color. If there are only chestnut and black, then the foal will be black. If there is an agouti gene to restrict the black to the horse's points, the foal will be a bay. If there are additional modifiers, the horse may have other attributes such as spots, dun stripes, etc. A chestnut of any kind cannot result from this mating, as this requires 2 chestnut genes, and a homozygous black carries no chestnut genes to pass along. the chestnut color is the most recessive gene, so all other colors will be dominant, but truthfully all colors come from an alteration or absence of a red or black gene. a homozygous black has two copies of the black gene, and will pass on one of them, the other gene will be chestnut, so the result will be bay, (red with black mane and tail) or brown (liver) or a black. A homozygous black is not possible. A good source to read about this matter is "Horse color explained" by Jeanette Gower.
It depends on the horse's genetics. Chestnut is recessive to black, therefore a chestnut horse always carries two chestnut genes but a black horse could be carrying two black genes OR a black and a chestnut, but the black is dominant therefore the horse has a black coat. Think of it as the black coat always sits 'on top' of the chestnut coat so if a horse has a black gene it will always show up but chestnut will only show up if there are no black genes at all. If you breed a homozygous dominant (two black genes) black horse to a chestnut, the foal will always be heterozygous dominant black. (One black gene and one chestnut gene) If you breed a heterozygous dominant (one black one chestnut) black horse to a chestnut, the foal has a 50% chance of being heterozygous dominant black and a 50% chance of being homozygous recessive chestnut. (two red genes) If you have no idea what your black horse's color genes are, think of it as having a 75% chance of a black foal, 25% chance of a chestnut foal.
