for a sheep to be born white, it must possess the dominant gene that switches color production off.  black sheep are a
minority and are seen as less desirable because black wool cannot be dyed for commercial production.   at one time the
english thought the black sheep was a sign of the devil.

it is sad to me that societies are so hell bent on there being a "norm" that we place negative labels on anything or anyone
that falls outside the parameters of normalcy.
