Figure 2. More genes are under-expressed in cavefish, regardless of rearing conditions.

Figure 2.

Genes with a higher (plus) or lower (minus) expression in cavefish in comparison to surface fish under both natural and light/dark conditions reveal a higher number of genes with a lower expression in cavefish regardless of the lighting condition. This pattern may indicate that the function of many genes is reduced in the cavefish compared to the surface fish. The replication of this pattern in the dark indicates that this pattern of under-expression in cavefish is conserved regardless of lighting condition.
