Okay, I'll give this a try. Lol. Appaloosa spotting patterns are governed by several genes in game, and we can only see two of them in gene testing. LP is the main gene that triggers the appaloosa patterns to show. Without LP, you get no appaloosa markings, but with it you can get anything from a blanket that may be so tiny it's almost invisible to one that may cover most of the horse, depending on the hidden genes and PATN1, which is testable and makes the effects of LP bigger and stronger.

One LP alone will make a small spotted blanket, sometimes so small the horse looks solid except for a speckled muzzle. One LP plus one PATN makes a large spotted blanket, and one LP plus two PATN makes a leopard with spots all over. Two LP with no PATN will make a small solid white blanket, two LP with one PATN makes a large white blanket, and two LP with two PATN makes a mostly white horse with only a few spots, usually with some color on the head, lower legs, and tail.

Spot size is definitely inheritable from what I've seen in my herd, but the genes that govern it are hidden. DP (the hidden gene that turns chestnut into liver) is one of the genes usually causing larger spots from what I see in my herd, but sometimes the other hidden genes that affect spotting can override that and still give you tiny confetti spots even on a liver. Lol

More pigment means more likely to get the larger spot size I think, but still yes there seems to also be a genetic proponent

ChristaOsar your first horse has two Lp genes, the second has one Lp. Homozygous Lp is often called few spot for that reason

Grey in real life increases spot size because of the pigment flood before going grey

Here's the larger spots from Hom Ssty and a DP as well.

Late Snowflake Varnish

A lot of the horses in Kintara's link are fully matured Varnish whether is regular varnish or Snowflake. So they come out white :)
