Figure 16-48Cortical inheritance of pattern in a ciliated protozoan

(A) Scanning electron micrograph of a Paramecium, which swims by synchronously beating its cilia. (B) Schematic diagram of the rows of cilia on the surface of a normal Parameciumand on a Parameciumin which rows of cilia have been inverted so that they beat in the opposite direction. Such altered patterns are propagated indefinitely as the Parameciumdivides, even though the information in the DNA is unchanged. (A, courtesy of Sidney Tamm.)
