The type of white pattern is not mentioned here...for the sake of simplicity I will assume that the stallion and mare are Tobiano for the first example.
Stallion aaE-Toto or aaE-ToTo
Mare --eeToto or --eeToTo (genetics of mare at agouti site is unknown and may
be determined to some degree by looking at the colors of the parents and grand parents.
If either the stallion or the mare is ToTo (homozygous for tobiano) 100% of the foals will be Tobiano and 50% of the foals from this mating will be homozygous for Tobiano.
If the Stallion is Ee at the extension site 50% of the foals will be chestnut.
If the Stallion is EE at the extension site there will be no chestnut foals.
The genetics of the mare at the agouti site will determine the color of any foals that are Ee or EE at the extension site.
Since the stallion is black: aa he can only pass the a allele to his offspring.
If the mare carries the a allele, 50% of the foals will be black.
OK, this is the general estimate. Not knowing what genes the horses were homozygous and heterozygous for, this is just a rough estimate: 33.34% - Black 33.34% - Bay 33.33% - Chestnut If you know the what the stud and/or the mare is homozygous and heterozgygous for, then you canget a more exact estimate if you go to the link in the relatedlinks.

Yes, it is possible for a chestnut Arabian mare bred to a black Arabian stallion to produce a grey foal. If either the mare or stallion carry the gene for greying, there is a chance that the foal may inherit this gene and develop a grey coat color as it matures.
Maiden mare: never been bred Open mare: had a foal but not bred back to a stallion Barren mare: bred or bred back to a stallion but not in foal
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
Well, an exact answer would require knowing what each horses exact genetic code was for their colors including the pattern for the sorrel mare (Tovero, Tobiano, overo, sabino, or splash.) also what was the stallions original color? Grey is a modifier gene that is typically inherited around 50% or more of the time.
50% chance of a creme dilute either a palomino, a buckskin or a smokey black based on the base coat color genetics of the parents. The sorrel mare could be AAee Aaee or aaee The buckskin stallion could be AAEe, AAEE, AaEe, or AaEe If the stallion is AAEE all foals will be bay or buckskin. If both the stallion and the mare carry an a allele a smokey black could be produced.
OK, this is the general estimate. Not knowing what genes the horses were homozygous and heterozygous for, this is just a rough estimate: 33.34% - Black 33.34% - Bay 33.33% - Chestnut If you know the what the stud and/or the mare is homozygous and heterozgygous for, then you canget a more exact estimate if you go to the link in the relatedlinks.
The exact color of the foal will vary according to the exact genetic coding of both parents and without that information it can be almost impossible to tell you what color a foal may be.
No. Bred mares are not receptive to the stallion because they are bred, not in heat.
If she has never been bred before, then she would be referred to as a maiden mare. If she has been bred before, but is not currently pregnant or raising a foal, she would be referred to as an empty mare or a dry mare. Otherwise, she is still normally referred to as a mare.
Yes a black and a buckskin can produce a buckskin according to the extension and agouti statues of each parent.

A mare can be bred as early as her first season which occurs between about 9 and 12 months of age. It is NOT recommened as she is still growing herself. And a mare can continue to breed into her 20's if in good health. A mare can produce one foal per year.
It depends. The breed of the horses involved, which coats are dominant in the breed, and wether or not the horses are purebred. For example, if you breed a purebred black horse to a pure brown Thoroughbred mare, then the foal will be black because black is dominant in the breed. However, this rule of coat domination is only true if the horses are purebreds.
Yes, it is possible for a chestnut Arabian mare bred to a black Arabian stallion to produce a grey foal. If either the mare or stallion carry the gene for greying, there is a chance that the foal may inherit this gene and develop a grey coat color as it matures.
Answer: You have to get a ultrasound when the mare has carried the foal for 8 months.
