New Hypothesis of the Cause of Cytoplasmic Incompatibility in Culex pipiens L.


IF males of one strain of C. pipiens are crossed with females of a strain from a different geographical area, the number of offspring may be either normal or small, or there may be none at all1. These three results have been called compatible, partially compatible and incompatible, respectively. Reciprocal crosses may give the same or different results. For example, strain A males may be fully compatible with strain B females, but strain B males may be compatible, incompatible, or only partially compatible, with strain A females.
