Without regard to anything else, at least one parent must be bay and one must be roan. That being said, the ideal way to produce a bay roan would be that one parent is homozygous for roan RnRn and one parent is homozygous for bay AAEE. or one parent is AAEERnRn. This would guarantee that the foal produced would be bay and roan...(assuming that no other dilution factors are
present).
If either horse is homozygous for roan the foal will be roan, if both are heterozygous there is a 75% chance that the foal will be roan. If by strawberry roan you mean the stallion is a bay roan as opposed to a chestnut roan, we can surmise that the stallion is Rn-A-E- The mare is Rn-aaE- The base color of the foal, without regard to whether it is roan is as follows If the stallion or mare is EE at the extension site they will produce either a bay or black foal...since the stallion is bay he could be AA (only bay foals) or Aa which will produce 50-50 bay or black with this mare. If both the mare and the stallion are Ee at the extension site there is a 25% chance of a chestnut foal.
A blue roan horse is not actually blue, though they can look blue. They have a mixture of black and white hairs that appear gray or "blue". They differ from gray horses because they are born blue and stay blue their entire lives. A gray horse is born a solid color, but gradually get more and more white hairs until they are completely white. It is sometimes hard to tell a gray horse from a blue roan. One way to tell is to look at the head and around the eyes. In a gray horse, they will go white around the eyes first. A blue roan horse will keep a nearly black head no matter what age they are.

You are likely to get a chestnuty/bay colour I think.
The genetics have everything to do with this. Supposing the mother is homozygous for roan and the sire is homozygous for dun, the foal would be either grullo roan, bay dun roan, or red dun roan. In the releated links is the website I used to calculate it. Play around with it a little and see all your options. Try seeing what will happen if the mare is heterozygous while the sire is homozygous, vice versa, and what if they are both heterozygous.
There are several different possibilities, depending on the genetic makeup of the parents. The base possibilities are: chestnut bay black The dilute gene (that makes the mare a buckskin) will give you: palomino buckskin smoky black The roan gene (that makes the sire roan) will give you: red roan bay roan blue roan If both genes are passed on, you get: palomino roan buckskin roan smoky black roan
Yes.
If the stallion carries the a gene and is heterozygous for roan your chances of a true blue roan are 50% if your mare is Ee. If she is EE there is no chance of a chestnut coated foal so the color of the foal will be controlled by the genetics of the stallion at the agouti site...either brown, bay or black.
There is no difinite way to tell, but it could end up being a chestnut overo foal. They foal could also get it from it's distance dam's or sire's (great grandsire, grandsire, great granddam, granddam).
Past colours in her family will have no say in her own offspring's colour. My buckskin mare has had her buckskin granddam and sire be bred to cremellos and produce palomino foals, so I thought she would too but instead I got a perlino, and the other three times I bred her to differant cremello stallions and yet again I got 2 perlinos and a buckskin. (Here the buckskin mare's sire and dam must be Ee at the extention site. Based on the results gotten by breedings of their daughter, there is a very high probability that she is EE at the extension site hence no production of palomino.) So no, you will not get a blue roan unless you specifically breed her to a heterozygous blue roan with a silver gene and make sure your mare is homozygous bay roan who has the silver gene as well but also has her black gene dominant over her red gene. f you know this info then you can assume your foal will be blue roan. But there is a 2% chance she will produce a throwback (a foal the same as a past grandsire/granddam/great-grandsire & dam) that may very well be blue roan. This can happen even if you bred her to a colour that would only produce, say, a chestnut. My buckskin's mother is a palomino and she was supposed to be bay according to genetics. But she was a throwback. In technical terms, the percentage of getting a blue roan from a bay roan mare and blue stallion is 17.58%, with the probability of bay roan being 52.73% Different take on this discussion: This mare is AaE-Rn- (unknown allele at the extension site and unknown allele at the Rn site). We know the second allele at the Agouti site is a because her sire was aaE-Rn- If the mare is bred to a blue roan stallion aaE-Rn- (again we don't know the disposition of the alleles for this stallion at the extension or roan sites). However, if either the mare or stallion is EE at the extension site there will be no chestnut or red roan foals produced from this mating. In this instance where either the stallion or the mare is EE at the extension site, there is a 50% chance that the foal will be black (aaE- or aaEE) and and 50% chance that the foal will be bay (AaEe or AaEE) in both cases there will be a 75% chance that the foal will be roan. 37.5% chance of blue roan (aaE-Rn-) 37.5% chance of bay roan (AaE-Rn-) 12.5% chance of bay (AaE-rnrn) 12.5% chance of black (aaE-rnrn) If both the mare and stallion are Ee at the extension site the percentages will change to include chestnut and red roan foal possibilities. If the stallion is homozygous for roan all foals produced from this mating will be roan with and 50% of the foals will be homozygous for roan. There is no information on the presence of the Silver or Taffy gene being represented in this breeding and it is not required to produce blue roan.
Typically a cremello or palomino crossed to a bay or black horse will produce a buckskin foal.
That depends on the color of the Paint stallion. Not the PATTERN, but the color other than white that is on the horse. The Paint pattern of the stallion and the white markings of the mare factor into whether the foal will have a Paint pattern, so I can't answer to that at all without more information.To answer about the color other than white that the foal might be.....If the Paint is chestnut or sorrel and white, the foal will be chestnut or sorrel.If the Paint is bay and white, the foal may be chestnut/sorrel or bayIf the Paint is black and white, the foal may be chestnut/sorrel, bay, or blackIf the Paint is palomino and white, the foal may be chestnut/sorrel or palominoIf the Paint is buckskin and white, the foal may be chestnut/sorrel, palomino, bay, or buckskinIf the Paint is cremello and white, the foal will be palominoIf the Paint is perlino and white, the foal will be palomino or buckskinIf the Paint is grey and white, you need to find out what color he was born. He would have been born one of the colors above (chestnut/sorrel, bay, black, palomino, buckskin, cremello, or perlino), then turned grey. Find out what color he was born, and then look at the list above. Your foal will be born one of the given colors, then have a 50% chance of turning grey. If the foal is going to turn grey, usually by 4 weeks of age they will have light hairs coming in around their eyes, on the muzzle, etc.If the Paint is dun and white, you need to figure out what the base color is and refer to the list above. The dun gene dilutes a base color, and is not passed along to every foal. Grulla is a black horse with the dun gene, red dun is a chestnut/sorrel horse with the dun gene, and "dun" is a bay horse with the dun gene. Palmino's with a dun gene are called dunalino, and buckskin's with a dun gene are called dunskin.If the Paint is red roan (chestnut/sorrel with the roan gene), your foal may be chestnut/sorrel, or red roan.Roan genes in Paints can be hard to figure out because the Sabino overo gene can make a horse look roan, when really they are not. A roan horse must have had a roan parent, so look at the color of the ancestors...if neither Paint parent was a roan, the stallion is not a roan either.If the Paint is a blue roan (black with the roan gene), your foal may be chestnut/sorrel, bay, or black and may also get the roan gene (red roan, blu roan, or bay roan)
