means An organism, cell, or gene produced as a genetic duplicate of another, or more loosely, any exact copy of something.

from From Greek 'klon,' meaning 'twig' or 'slip' — the small cutting a gardener snaps off a plant to root and grow into an identical new one. Botanists borrowed the word in the early 20th century for plants propagated this way, and from there it spread into genetics to describe cells or organisms copied from a single ancestor, before leaping into everyday speech for any dead-ringer duplicate.
