Chimera (when one twin absorbs the other)
This horse is a chimera, not a true brindle. The horse is Dunbar’s Gold. His pattern is caused by the fusing of twin embryos in the womb who were of two different colors. They found this out when he was bred to another brindle mare and the foals dna didn’t match either parents records. There are some true brindle producing stallions out there, but they are very rare.
