You were confused because genetics of color is absolutely confusing. In most modern breeds black sheep have been bread out of sheep for years yet they still show up occasionally.
Most modern domesticated sheep are white. They mostly have Awt/Awt for their Agouti genes, telling their bodies to produce no black/brown pigment. But once in a while a black sheep turns up in an all-white flock, and it's not necessarily the result of a ram jumping the fence. Instead, it's the result of a recessive pair of genes at a different location, called 'extension'. A sheep which has Awt/Awt and Ed/E? will be colored! The Ed/E? influence cancels out the Awt/Awt influence and allows the action of yet another gene, BB/B? to show up on the sheep.

Having black wool is a recessive gene that appears. You would need to to study dominate and recessive genes to understand the process.

Your question is just the inverse of the question of why do most of the sheep have white wool.

My guess is that its the same reason there are different races in our society.
