Study on karyotype and occurrence of B chromosomes in two endemic species of the genus Pimelodus (Siluriformes, Pimelodidae) from the river Iguaçu.

Hereditas - 1 Jan 2004

Borin Luciana Andreia, Martins-Santos Isabel Cristina

Abstract excerpt

The current work describes, for the first time, the occurrence of B chromosomes in the genus Pimelodus. Cytogenetic analysis in P. ortmanni and Pimelodus sp., from the river Iguaçu basin, revealed a diploid number of 56 chromosomes. Whereas distribution pattern of C-banding in Pimelodus sp. showed predominance of heterochromatin at the two extremities of several pairs of chromosomes, centromere markings...
