英文摘要
Possible involvement of "apomixis", which causes clonal reproduction and polyploidy in plants, was investigated in sturgeon species. Genome size estimation by DNA content flow cytometry and molecular cytogenetic analyses including FISH clearly showed elevation and reduction of ploidy status among different species as well as occurrence of genetic diploid and tetraploid in artificially propagated con-specific and hybrid progeny. The results suggest ploidy variation should happen in present sturgeon species.
