Heterochromatin, sex chromosomes and rRNA gene clusters in Coprophanaeus beetles (Coleoptera, Scarabaeidae).


Repetitive DNA sequences constitute a high fraction of eukaryotic genomes and are considered a key component for the chromosome and karyotype evolution. For a better understanding of their evolutionary role in beetles, we examined the chromosomes of 5 species of the genus Coprophanaeus by C-banding, fluorochrome staining CMA₃/DA/DAPI, and fluorescence in… (More)
