| fish with whole chromosome and telomeric probes demonstrates huge karyotypic reorganization with its between two species of oryzomyini (sigmodontinae, rodentia): hylaeamys megacephalus probes on cerradomys langguthi karyotype. | rodentia comprises 42 % of living mammalian species. the taxonomic identification can be difficult, the number of species currently known probably being underestimated, since many species show only slight morphological variations. few studies surveyed the biodiversity of species, especially in the amazon region. cytogenetic studies show great chromosomal variability in rodents, with diploid numbers ranging from 10 to 102, making it difficult to find chromosomal homologies by comparative g bandin ... | 2013 | 23494775 |
