She is quite special. 
I never thought genetics could be so interesting! I think I get it! Thank you so much, so is there such a thing as a white basecoat on any coloureds ever? or are they all dark with white? x
He is not a "drum cob" though. A cob is a small, or should that be short, horse and a drum horse is big as in the Drum carrying horses of cavalry bands which are typically 17hh.
Drum horse has become a scam the Yanks phrase for oversized cob.
I was just going to ask what a 'drum' horse is, so Thankyou Sugar.
I presumed it was just a title/description for a big horse that actually carried the drums. Like any carriage horse is a carriage horse because it pulls a carriage, or a lead rein pony a lead rein pony blah, blah, blah - regardless of its' actual forebears.
DD, how big is your boy going to make?
To my eyes he is a skewbald, to North Americans he would be a bay (or, more likely, red and white, if they weren't being fussy about his black tips) tobiano, although some may argue tovero (does he have a blue eye?)

I'm not totally up on the North American terms, but I believe (the internet doesn't lie... right?) that Toveros have tobiano + a non tobiano (AKA overo) coloured gene. So that would make DD's Freddie a Tovero because he probably has tobiano and sabino.
Lol Faracat have you changed your diagnosis????
