摘要：

The relative frequencies of heterokaryons and the two kinds of homokaryons have been scored among colonies from conidia harvested from a heterokaryon and treated with UV, in order to determine which kinds of lethal mutations were induced. Recessive lethal mutations were scored directly. The pattern of surviving types indicated that recessive lethals and mitotic lethals (events destroying whole nuclei) occurred with similar frequencies. But the absolute frequency of these mutations was not sufficient to account for the observed kill, suggesting that dominant lethals and/or cytoplasmic lethals were also induced at a similar rate. © 1979 Springer-Verlag.
