Beschreibung:
<p>The phenomenon of segregation-distortion, originally discovered in Madison, Wisconsin, has now been detected in a natural population of Drosophila melanogaster from Baja California. It has been demonstrated that the second chromosome responsible for the aberrant segregation is an SD-bearing chromosome, because it shares the following properties with the Madison SD: (1) It is expressed in the male sex only. (2) It is inhibited by the Curly inversion. (3) The Baja California SD chromosome is not sensitive to the action of the Madison SD chromosome. (4) It is located near the centromere (closely linked to cn). This finding suggests that SD is not of recent origin.</p>
