You ladies are ssooooo funny!!! Totally smiled and laffed thruout this thread. It's great!
The two bubbies are gorgeous. It will be interesting to see if Scarlett stays chestnut/white or eventually goes grey. I can't tell on her brother with that lovely shade of bay he is...
As to your ??ing the red - just means that not only is your stallion heterozygous for black but so are both of those mares. You also know that Nick is heterozygous for tobiano since Cam is solid. So Nick's color genetics look like this - Ee,aa,Tt - he isn't bay so he has the two little a's. There probably isn't anything else in Nick's coloring - but not positive about that.
Since Pnut is grey but had a solid bay - she is also heterozygous black w/ at least one grey gene - EeA?G?. EDIT- she could have been chestnut/sorrel - eeA?G?. EDIT. That one headshot of Cam, I would swear that he was going to go grey, but then the rest - don't know for sure. Love his bay coloring!! My bays don't seem to have that pangare gene and are predominantly a bright red shade. I have had a couple that are very, very dark bay and one who is considered a "black bay" by Arab world (could be a dark smutty bay? Currently no way to test for "smutty".). If both of her Pnut's turn grey later - then you are back to not knowing as she could have only one grey gene and still always have a grey foal, since each time you would have at least a 50% chance of grey. Any horse that gets a "G" is going to be grey(shade out to solid "white" ), eventually. Also, need to put a ? on her bay gene as she could be homozygous for bay. You can't tell on a chestnut if they got the bay gene or not. Do you know if she was a pinto when born?
And the bay tobi mare is EeA?T?. Sneeker could carry a bay gene from his dam - you know that he doesn't get one from his sire - ee, a?, T?. Scarlet is ee, a?, T?, g? ...
It's really cool that you got two similar shade chestnut foals with similar Tobi markings in the same year!! Isn't color a weird and fascinating subject? Who knows - as more info is found out about colors, that may change the genetic "look" of your minis (the lettering and what they can produce).
Didn't I read somewhere on this thread that you have one more foal coming? What is that momma like?? Is your other mare the chestnut and white I saw in at least one photo? Or is that another mini?
IF Nick is bred to a chestnut mare, you still have a chance of a black based foal - because he has one black gene himself (E). The chestnut mare will always pass on a red gene (e)...
That is how I got a black colt out of a chestnut mare that I have. Actually we knew the foal would be black based because his sire is homozygous for black - but he'd only get the little e from his dam. So our colt is Ee, aa (he's not bay, so even tho his dam carries a bay gene, he didn't get it). His sire is homozygous for Tobi so we know that he has one T, but his dam is hetero so we don't kno until we test whether he got two T's. If our colt remains a stallion, and we breed him to some of our current mares - we can get chestnut babies. We can get chestnuts that are silver and bay carriers. OR we can get silver black or silver bay, or no silver at all.
The one filly I got this year, the 3rd for the same cross, looks like she MAY be homozygous for Silver. So exciting - I haven't had her tested yet. I've been surprised how hard it can be to get the homozygous Tobianos and Silvers! Even when breeding a homozygous Tobi (TT) to a heterozygous Tobi Tt) - 100% chance of Tobi, 75% of homozygous, but with my crosses only getting Tt. Our current stallion is Zz (silver), and even when bred to a ZZ mare, I've only gotten heterozygous Zz. This is an older mare and didn't produce a foal this year and not sure she will later. According to some of the research I've done - the T gene can lock onto one or the other of the black gene of an Ee horse - meaning that every bay/black foal is Tobi and chestnut foal is solid or vice versa. I didn't breed any mares back this year - as we can only feed/care for so many and now I have 8 acres full of ponies... Again, color is so fascinating!!
