Q18. A clone is a colony of: (a)cells having different shapes (b)cells having similar shape (c)cells having similar genetic constitution (d)cells having different genetic constitutions
Option C) 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).
