QTL mapped in a cross between surface and Pachón cave fish cluster in the genome. Vibration attraction behavior (VAB)2 and VAB17 are redrawn from Figure Three of Yoshizawa et al.. These are aligned with the homologous linkage groups LgP07 and LgP17 from Protas et al.. The black bars show the locations of QTL mapped in the crosses. QTL traits are as follow: C, condition factor; D, depth of the caudal peduncle; Eye or E, eye size; M, number of melanophores; R, number of branched anal fin rays; S, number of SO3 bones; SN EO, superficial neuromasts in the eyeless orbit; T, number of maxillary teeth; VAB, vibration attraction behavior; W, rate of weight loss on fast. QTL mapped on LgP07 and LgP17 are from  and . Methods for mapping QTL and for detection of multi-trait QTL are given in . EMRDS is a multi-trait QTL with significant correlation to variability in Eye size, numbers of Melanophores, number of anal fin Rays, Depth of the caudal peduncle, and number of So3 bones. Similarly, EMT is a multitrait QTL with significant contributions for Eye size, numbers of Melanophores and numbers of maxillary Teeth.
