Sorrel Mare would be --ee (-- is unknown genetics at the agouti site and ee is
homozygous recessive at the extension site.
Buckskin Stallion is A-E-Crcr or A-EECrcr.
Since the e allele is generally at a very high frequency in most horse populations we'll assume that the stallion is A-EeCrcr.
50% of all foals will be red based, either palomino or sorrel
50% of all foals will be non-red based, either bay or buckskin
A sorrel horse is a reddish colored chestnut. Genetically speaking, the horse is Red.
Whatever colour either of the parents are the foal could be, and it could just be any random colour, but the most common is the colour of either of the parents.
It is never too late to check a mare in foal, until after the mare has foaled.
Yes, because if you have a grey mare or stud whose base coat color was a dilute color such as palomino 0r buckskin before they turned grey, then that horse is bred to a dilute colored mare, the resulting foal could be a cremello that is also carrying the grey gene. Therefore, cremellos and perlinos can, if they are out of a grey parent, produce a dilute foal that turns grey. UC Davis now offers the genetic testing for the grey gene, so any cremellos or perlinos out of grey parents should be tested before being touted as 100% dilute color producers, or mare owners will be greatly disappointed!
Mare
Usually the darker color will be dominant in horses. BUT... sometimes the horses genes will override this color dominance. It is a sort of wait and see with horses. It all depends on the genes that the parents carry. If there is a bay (brown with black mane/tail/legs) in either the mother or the father's genes, it is possible to produce a buckskin. The special thing about palominos is that the cream gene (that makes them that gorgeous gold colour) is a dominant gene. That means you only need one copy of that gene for it to influence the outcome of the offspring. Think of it like a dilution. A chestnut horse bred to a cream/cremello or (anything carrying the cream gene) will most likely produce a palomino foal. A bay bred to cream gene carrier will most likely produce a buckskin. A black bred to a cream gene carrier will most likely produce a smoky black. However, with all these cases, there are exceptions. If the mother or the father has a bay parent or grandparent, or the father has a buckskin parent or grandparent (because, remember, the cream gene is dominant, so if the mother isn't palomino/buckskin/smoky black, she won't have the crema gene in her lineage), and remnants of those genes have been carried forward into the mare or stallion, there is a chance you'll have a buckskin foal. Yes, it is very confusing ^^ This is a really good site to check out what colour foal you'll get from what colour parents: http://www.animalgenetics.us/CCalculator1.asp
palomino
Most likely would be cremello, palomino, chestnut (sorrel) or another buckskin.
Yes, if "white" means gray...there would be a 50% chance of any foal produced having the gray gene. Whether the foal will be chestnut, buckskin, bay or palomino will hinge on the genetics of the mare. If "white" means maximum expression sabino...then there is a white component that is independant of the possible colors. Again the foal could be chestnut, buckskin, palomino or bay will hinge on the genetics of the mare.
Well possibly, this would mainly depend on the color of the mare. Buckskin is a dilute color and will dilute the base color of a horse (Bay + Cream= buckskin etc,).
Buckskin or Smoky Black
Yes.
Because there is no true "Gray" color, but actually a base color that grays with age, one would have to know the base color of the dam (mare) before being able to give any sort of prediction of foal color.
Whatever colour either of the parents are the foal could be, and it could just be any random colour, but the most common is the colour of either of the parents.
However, you can veiw the chances of each color with this Foal Color Calaculator in the relatred links. The calculator said the following when I entered in the mare and the stud coats Offspring Color Probability 43.95% - Buckskin 43.95% - Bay 3.13% - Palomino 3.13% - Chestnut 2.93% - Smoky Black 2.93% - Black However, there were options to specify. It asked for Red factor and the Agouti, whether it was heterozygous or homozygous. I did not know these specifics, so I left it as unknown, which is why I advise you go and experiment. See what would happen if the stud was homozygous, or if the mare was homozygous, or if she was heterozygous, etc. YOu can only know with the vet usually....but its unknown...you wont know until the foal is born sorry.
yes. as long as one of the parents has a pinto/paint breed/coloring you can get a paint foal
A mare that has a foal is called a broodmare.
Since the term creme is used (the assumption here will be that the stallion is a cremello which is a chestnut colored horse with two Creme genes). We know this stallion is ee at the extension site and CrCr at the creme site. We dont' know what the genetics of the stallion is at the Agouti site but the genetics here would come into play in the color of the foal if the brown mare passes an E allele to the offspring. A general idea of the color possibilities can be determined by looking at the color of the parents of the stallion in an attempt to assertain his genetics at the Agouti site. The mare will be the brown horse in this example. Brown in the strictest sense is a horse that is At- (at the Agouti site) and Ee or EE at the extension site. If either of the brown mare's parents was a chestnut the mare is At-Ee. If either of the brown mare's parents was a true black the mare is AtaEe orAtaEE. If both the mare's parents are brown study of the various colors of the parents and grandparents of the mare may give some insight into the genetics of the mare. Since the e (red) allele has a very high frequency in most horse populations we will assume that the mare is At-Ee. Bred to a cremello stallion who is --eeCrCr 50% chance of the foal being palomino --eeCrcr 50% chance of the foal being some type of dilute because it is Ee at the extension site. This could be buckskin, smokey black, sooty buckskin. If the mare is EE at the extension site any foal produced from this mating will be buckskin, smokey black or sooty buckskin depending on the alleles present at the Agouti sites of both parents. Simplest way to know what you'll get is if the stallion and mare are color tested. The stallion would only need testing for info on the Agouti site. The mare would need to be tested for Agouti and Extension.
