Genic Conversion in Oenothera? A Critical Review
Preview not available

Abstract

The remarkable facts found by Renner and Oehlkers in Oenothera crosses involving the cruciata character (calycanthemy) are reviewed and the interpretations of both authors confronted. It is shown that the facts require an unusual genetic behavior which, for Renner, is the process of genic conversion. It is discussed that recent findings in Drosophila point to the possibility that the apparent conversion is in fact unequal crossing over in a duplication, which might be controlled by a specific genetic condition comparable to Dt and Ac in maize. It should be difficult to prove any interpretation in a material like Oenothera.
