What is it about?
We describe the karyotype of Elaenia spectabilis (Passeriformes, Tyrannidae) by means of classical and molecular cytogenetics. The results show that syntenic groups of Gallus gallus (GGA) were conserved, except GGA1 and GGA4, which were divided into two different pairs each. However, the results obtained with Leucopternis albicollis probes revealed the occurrence of inversions in segments homologous to GGA1q, similar to those observed in other Passerifomes (Turdus), and one inversion in GGA1p. These results suggest that the centric fission in GGA1 and inversions observed in segments homologous to GGA1q, appeared in the early history of Passeriformes because they could be detected in Oscine and Suboscine species.
