THE INFLUENCE OF CYTOPLASMIC POLLEN STERILITY ON GENE EXCHANGE BETWEEN POPULATIONS.

Abstract

The behavior of cytoplasm and plasmon-sensitive genes producing, in combination, pollen sterility has been reinvestigated taking into account gene flow between populations. It has been repeatedly suggested that cytoplasmic pollen sterility may give rise to a mating barrier which would tend to inhibit gene exchange between populations and in this way initiate speciation. This investigation confirms the findings of an earlier paper (Watson and Caspari, 1960) that there is no basis for this belief. (Author)
