In Situ Gene Mapping of Two Genes Supports Independent Evolution of Sex Chromosomes in Cold-Adapted Antarctic Fish
Figure 2
C. hamatus and P. macropterus reversed black and white DAPI- stained metaphases ((a) and (b), resp.) and C-banded chromosomes ((c) and (d), resp.). The sex chromosomes are labeled in the metaphase plates and shown enlarged separately in the boxes. The presumed X1 and X2 have been identified according to morphology, size, and banding pattern. Scale bars = 10 μm.
