Here are the foals I've had from just one of my appaloosa mares, who is a red roan with just a couple of white appy spots, and appy characteristics. She's pictured hairy (not clipped at all).
Wild Winds Frost Fire, pictured with one of her more recent foals.
Frost's first foal was by a blue roan appaloosa stallion who had a blanket and spots. She had a blue roan appy filly with a huge blanket and big spots. Pictured here is Frost with that filly as an older broodmare.
Her next foal was by a leopard appaloosa, and she foaled a blue roan appaloosa colt with blanket and spots:
Her next foal was by the previously-mentioned blue roan appaloosa stallion, and she had a colt that was born looking sorrel with a blanket, but who, when clipped out, looked white. He had mottling, sclera, etc.
Her next foal was sired by a near-leopard appaloosa. This stallion sired only three foals for me, and only one had appaloosa coloring at birth, the other two (fillies) were solid black. This mare is still solid black as a five year old, but she does have quite a bit of white in her tail, and some white hairs scattered throughout her body, and sclera.
Her next foal was sired by a black and white pinto stallion, no appy breeding. Her resulting colt was born black, with appy characteristics, and by the time he was two years old had snowflake spots all over his body. Sorry I don't have a picture of him colored out on my computer.
Her next colt was sired by a solid (no appy breeding) dark bay ASPC/AMHR stallion. This colt was born with the blanket and spots.
Her next foal was a filly by a silver bay minimal sabino ASPC/AMHR stallion. This filly has some odd markings, such as large "chocolate" colored patches on both sides of her lower abdomen. I'm not sure what they are. She has striped feet (tho those could be attributed to the silver, as she is also a silver bay like her sire). Appy or not appy, I'm still not really sure (but I LOVE this filly)
The sire of the previous filly died just days after the filly's birth (devastating to me) and I was without a stallion, so I went back to the owner of the stallion (leopard appaloosa) who sired this mare's second-born, and they produced a full sister to my blue roan appy gelding. She was born jet black with white hooves, which subsequently have striped, and she has a LOT of mottling now as a yearling.
and her most recent foal, who is by my leopard stallion, CCMF Spotted Illusion:
This is a black snowcap colt.
It's interesting to see the variety of colors that this mare has produced, and to see that some of her loudest colored foals were by non-appy sires.
