Working backwards here! I have a fleabitten grey mare. She looks as if she would have had a bay base. I have been told that her dam was also grey, unknown if she was fleabitten. What possible colour combinations could have been found in the sire?
^ Pretty much.
Grey takes over any base color and fleebitten is not always a guarentee, it's just something that occurs, depending on how that particular horse greys out.
Also, black is always dominant over red when it comes to genetics in horses, so your mare could have got her black gene and agouti from either side.
It's possible that the sire could have been a bay, a black (or any variation) or even sorrel
It would only help to know what the dam was as well, though you could still determine little from that without testing.
It's extremely difficult to figure out color backwards like that. The only 100% for sure color combination is chestnut + cremello = palomino, anything else could really have an extensive list of colors because, for example, a horse could be a buckskin dun, but not pass on ANY of of the modifying genes (agouti, cream, and dun) to a foal.
I forgot to ask--does it change the equation any if I mention that all horses in the scenario are purebred Arabians? Polish, to be a little more exact.
Yeah a little, Arabians only come in certain colors, purebred ones at least. Sorrel, bay, black, and grey, (well I think they are discovering dominant white but I haven't read on that yet but that's unlikely a choice in your case) so you can maybe guess based on that. Posted via Mobile Device
So I still need to do a little bit of DNA testing, don't I?
Thanks again!
