Sequence changes in the surface fish and cavefish αA-crys gene loci. A. A schematic diagram of the sequenced Texas surface fish (SF) and Pachón cavefish (CF) αA-crys loci showing the positions of four sequence changes (see Table 1). CßSA: last cystathionine-ß-synthase a exon. E1-3: αA-crys exons. B. Alignment of αA-crys loci in 5 teleost species with Astyanax Texas surface fish αA-crys shows 10 conserved regions (black bars labeled 1 to 10 on top of frame) but their sequences are not changed between surface fish and cavefish (Table 2).
