A karyotype comparison between two species of bordered plant bugs (hemiptera, heteroptera, largidae) by conventional chromosome staining, c-banding and rDNA-FISH
A cytogenetic characterization, including heterochromatin content, and the analysis of the location of rDNA genes, was performed in Largus fasciatus Blanchard, 1843 and L. Rufipennis Laporte, 1832. Mitotic and meiotic analyses revealed the same diploid chromosome number 2n = 12 + X0/XX (male/female)...
