Figure 6.

Morphometric analysis of medaka inbred strains. (A) Four lateral (L1-L4) and five dorsal (D1-D5) morphometric distances were extracted and analyzed for each inbred strain. (B) A bar chart showing the proportion of variance explained by the difference between strains as a fraction of the total variance. The variables are the measurements corrected by the appropriate body length measurement (L4 and D5, respectively). (C) Example pictures showing substantial differences in lateral length and eye diameter between fish from the two Southern inbred strains HdrR and Icab. (D) Box plots showing the distribution of eye diameter, lateral length, and the ratio between eye diameter and lateral length for HdrR and Icab. Eye diameter and lateral length: y-axis = value in pixel. HdrR (n = 70), Icab (n = 78).
