• To examine the hybrid origin hypothesis of Rana porosa porosa cytogenetically, the lampbrush chromosomes of triparental allotriploids comprising the genomes of R. nigromaculata, R. p. brevipoda, and R. p. porosa were investigated together with those of their intra- and interspecific hybrids. The behavior of their homologous lampbrush chromosomes provided little evidence that chromosomal material from R. nigromaculata is present in the genomic chromosomes of R. p. porosa. On the contrary, it is suggested that R. p. porosa and R. nigromaculata are phylogenetically more distant than are R. p. brevipoda and R. nigromaculata.
