Chromosomal mapping of the type I and II NTS in Engystomops freibergi and Engystomops petersi. Karyotypes of E. freibergi (A), E. petersi from Puyo (B-C), and E. petersi from Yasuní (D-E) hybridized with probes for type I (B, D) and type II (A, C, E) NTS. Arrows indicate secondary constrictions of the NORs. The morphological difference between the Chromosomes X in C is due to a heteromorphism of a terminal C-band (for details about this heteromorphism, see [33]).
