Starshine, depends on what you want in genes. If you want to have more Roans then she will do that if you pair her with the right stallion. She's also Pangare which gives her a lighter coloring under her belly and muzzle,With the PATN gene she would probably pass on some neat markings for face and legs.
Starshine There isn't much to note, considering she's only a blue roan. She's EE aa, which means she will always produce a black based horse. There's PATN2, which she is hiding because she doesn't have the Lp gene (which would make her an appaloose), so she will pass on PATN2 to any offspring she has :) but that's about it
And the roan. She has a 50% chance of passing on her roan gene
