Black sheep

In the English language, black sheep is an idiom used to describe an odd or disreputable member of a group, especially within a family. The term stems from the genetic effect in sheep whereby a recessive gene occasionally manifests in the birth of a sheep with black rather than white coloring; these sheep stand out in the flock and their wool was traditionally considered less valuable. The term has typically been given negative implications, implying waywardness.
