An ideal cell marker should (1) be expressed in all descendants of a cell; (2) be present in all cells of a tissue or organism; (3) be cell auto

Other kinds of genetic mosaic, namely those arising through forward and reverse mutation at particular loci, can also provide useful information. This is particularly so because the initial mutational event in these mosa
