Misty's Sirocco

This little guy's owner Kendy with the 𝑪𝒉𝒊𝒏𝒄𝒐𝒕𝒆𝒂𝒈𝒖𝒆 𝑷𝒐𝒏𝒚 𝑫𝒓𝒊𝒍𝒍 𝑻𝒆𝒂𝒎 asked me to go through his genetics since they're quite interesting! Misty's Sirocco isn't color DNA tested yet, but both of his parents have been.
Sire, Ace's Tidewater Promise: A/a, E/E, nd2/nd2, TO/n, CR/n
Dam, Misty's Storm Chaser: a/a, E/e, nd1/nd2, TO/n

Sirocco is black like his dam but the why is a bit more interesting. Misty's Storm Chaser carries recessive chestnut from her chestnut sire Cezanne. Ace's Tidewater Promise is homozygous for black so he can only sire bay, black, buckskin, and smoky black foals. Despite Chase's recessive chestnut the pair of them could never have produced a chestnut or a palomino.

It's pretty common for black foals to look a bit...weird. That greyish color he had as a newborn and the faded looks he's gone through is pretty common for black foals. Black foal coats bleach pretty badly in the sun so when I get to see him later this month he'll look pretty faded! He's pretty sunbleached in his 3 month birthday photo a few days ago.

Sirocco's sire is a buckskin and I'm pretty positive he inherited his sire's cream dilution. That makes him a smoky black. Cream dilutes red pigment so it has little to do on a black, but Sirocco gave us a big hint. If you look closely at Sirocco's newborn photos he had dark blue eyes. Those are baby blues and have now turned brown. Baby blue eyes are found on foals with the cream dilution: palomino, buckskin, and smoky black. Not all cream dilute foals have baby blue eyes but some like Sirocco do.

It used to be theorized that black foals with light colored hair in their ears was a sign they are smoky black. You can see the light colored hair in Sirocco's ears in the second photo. This theory has been found to be incorrect. What was found is that black foals with that colored hair in their ears have non-dun1. Sirocco's dam Storm Chaser was tested to have non-dun1 so he probably has it too. His dam had that when she was a foal.

Both of Sirocco's parents are tobiano pintos and their DNA tests showed that both of them each have one copy of tobiano. Thanks to random chance neither of them passed tobiano on to him.
