Paramecium aurelia

  • Chapter

Abstract

A year or two before Morgan began his classical investigations on the genetics of Drosophila, Jennings—looking for a favorable organism for genetic research and appreciating the potential values of microorganisms for such work—began to study the genetics of Paramecium. Two decades later, he (Jennings, 1929) critically summarized—with full bibliography— the genetic results obtained in research on Paramecium and other unicellular organisms, including bacteria. During this period the work on Paramecium was, for technical reasons, restricted to two areas; but from each, important generalizations emerged. Studies in the first area, the genetics of asexual reproduction, led Jennings to put forth the basic concept of the genetic uniformity of the clone, i.e., the Pure Line Theory for Asexual Reproduction. Studies in the second area, the genetics of sexual reproduction (conjugation), led Jennings to calculate and generalize the Mendelian results expected from various systems of breeding. The publications that developed these formulae were among the earliest (1912–1917) basic contributions to mathematical and population genetics. [For full bibliography of Jennings’ publications, see Sonneborn (1975a).]
