Figure 1From: The key role of repeated DNAs in sex chromosome evolution in two fish species with ZW sex chromosome systemGiemsa-stained female karyotypes of Leporinus reinhardti (2n = 54) and Triportheus auritus (2n = 52), both with a ZZ/ZW sex chromosome system. The chromosomes of both species were arranged in descending order of size and the sex chromosomes were highlighted in boxes for the sake of clarity. Bar = 5 μm.Back to article page
