From: Long-time evolution and highly dynamic satellite DNA in leptodactylid and hylodid frogs
Karyotypes of Physalaemus species hybridized with the PcP190 satellite DNA. Karyotypes of (a) P. albifrons, (b) P. albonotatus, (c) P. centralis, and (d) P. ephippifer. In P. ephippifer, the inset shows the stronger signal from the W chromosome and the weaker one from the Z chromosome, as well as the distinction between the PcP190 and NOR regions detected by the Ag-NOR method (the signal was artificially colored green in the combined image shown in the inset).
