Well, here are the results from Evan's Software genetic What-If:
Chestnut- 29.97%
Otter (black)- 7.71%
Sable Agouti- 5.29%
Sable Chin- 5.29%
Chin Black- 5.29%
Opal- 4.42%
Orange- 3.71%
Golden- 3.71%
The rest of the colors are really low, so didn't include them. And also note, Evans isn't exactly 100% on their predictions, but it's been pretty good with my Flops.
