Abstract
The movement was investigated of a specific chromosome in the F1 progeny of the basidiomyceteCoprinus cinereus. We focussed our attention on the smallest chromosome of the 5302 strain. We first constructed a chromosome-smallest library and screened it with a chromosome-specific clone, pRC 1. The pRC 1 probe hybridized only with the smallest chromosome of the 5302 strain, and it detected one band of different mobility in two parental strains. In the F1 progeny, the probe hybridized with one to three chromosomes. Most of the hybridized chromosomes in the F1 progeny were positioned in terms of mobility between the hybridized chromosomes of the two parental strains. Therefore, they were probably generated by meiotic recombination between homologous chromosomes of different sizes.
