Map of human chromosomes (blue, right side) and S. oedipus (red, left side) in the G-banded karyotypes of C.a. paraguayanus (A), C.a. robustus (B), C. albifrons (C) and the human probes in C. olivaceus (D). Some syntenic groups have a small letter (e.g., a, b or c), according to the pattern established by Neusser et al. (2001). Groups without this letter correspond to whole chromosomes or chromosome segments that differed from those described by Neusser et al.
