S ummary A strain of Sordaria fimicola carries a reciprocal translocation which results in the formation of aborted ascospores in perithecia hybrid between this and the normal strain. Petri‐dish populations of the two strains were propagated by ascospore samples and the frequency of hybrid perithecia formed in each generation was followed. It was found that there was a rapid decrease in their frequency over eight generations. This was accounted for by the progressive elimination of normal nuclei by natural selection. Reasons for this selection are discussed.
