In Situ Gene Mapping of Two Genes Supports Independent Evolution of Sex Chromosomes in Cold-Adapted Antarctic Fish

Table 2

Presence () or absence (×) of 5S rDNA (C1) and AFGP (C2) genes on the Y chromosome of Antarctic notothenioid species after FISH. In columns C3 and C4 diagrammatic representation of the chromosomes bearing the two probed genes. The chromosomal bands indicate the position of the 5S rDNA (C3) and AFGP (C4) genes resulting from FISH analysis. (—) data lacking.
