A clone is a colony of cells having similar genetic constitutions. A clone is a group of identical cells that share a common ancestry, meaning they are derived from the same mother cell A somewhat similar concept is that of CLONAL colony (also called a GENET), wherein the cells (usually unicellular) also share a common ancestry, but which also requires the PRODUCTS of clonal expansion to reside at one PLACE , or in close proximity. A clonal colony would be well exemplified by a BACTERIAL culture colony, or the bacterial films that are more likely to be found in vivo (e.g., in infected multicellular hosts).
