| Abstract: | The sexually compatible strains ofCoprinus cinereus 5302 and Dd 13 revealed chromosome length polymorphisms in their electrophoretic karyotypes. The dikaryon derived from two monokaryons contained a mixture of the two electrophoretic patterns. F1 progenies were isolated by crossingC. cinereus 5302 and Dd 13 strains and it showed unique karyotypes. Chromosome length polymorphisms of both parental strains were inherited at random in the F1 progenies. As a result, several novel electrophoretic karyotypes which had not been observed in either parental strains were found in the F1 progeny. The rDNA probe hybridized with one chromosome in both parental strains, with two chromosomes in the hybridization pattern of both parental strains in the dikaryon, and with one to two chromosomes in the F1 progenies. The relation between mating type and hybridization pattern has thus not been made clear in the case of F1 progeny. |
