I am not 100% sure if this is a palomino but I just love the picture.
I know that this is not a "true" palomino color but I have read that palomino is not a breed of horse, and never could be, because the palomino color does not breed true.
A palomino is heterozygous-- meaning it has only one cream gene-- so two that are crossed have a 25% of producing an offspring with no cream genes (a red chestnut), 25% of producing an offspring with two cream genes (a cremello), and 50% chance of producing another palomino (one cream gene).
On the other hand, crossing a cremello with a chestnut gives 100% palomino foals. So when I look at the foal I would argue the case.
The horse is one of two extant subspecies of ''Equus ferus''. It is an odd-toed ungulate mammal belonging to the taxonomic family Equidae. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature into the large, single-toed animal of today. Humans began to domesticate horses around 4000 BC, and their domestication is believed to have been widespread by 3000 BC.
