==History==

'''Cortical Inheritance''' or structuralStructural inheritance was discovered by [[Tracy Sonneborn]], and other researchers, during his study on [[protozoa]] in the late 1930s. Sonneborn demonstrated during his research on [[Paramecium]] that the structure of the cortex was not dependent on genes, or the liquid cytoplasm, but in the cortical structure of the surface of the ciliates. Preexisting cell surface structures provided a template that was passed on for many generations.<ref name="pmid16554410">{{cite journal | author = Preer JR | title = Sonneborn and the cytoplasm | journal = Genetics | volume = 172 | issue = 3 | pages = 1373–7 |date=March 2006 | pmid = 16554410 | pmc = 1456306 | doi = | url = | issn = }}</ref>

John R. Preer, Jr., following up on Sonneborn's work, says, "The arrangement of surface structures is inherited, but how is not known, Macronuclei pass on many of their characteristics to new macronuclei, by an unknown and mysterious mechanism."<ref name="pmid9071578">{{cite journal | author = Preer JR | title = Whatever happened to paramecium genetics? | journal = Genetics | volume = 145 | issue = 2 | pages = 217–25 |date=February 1997 | pmid = 9071578 | pmc = 1207789 | doi = | url = | issn = }}</ref>
