Table 1 (a) Mean bilateral asymmetry and standard error (in parentheses) for three traits in Gila topminnows for wild-caught specimens from Monkey Spring (MS) and Sharp Spring (SS), where N is the sample size. Below are given the extent of asymmetry for the same three traits for laboratory-raised fish (b) from Sheffer et al. (1997) (S et al.) and (c) from Quattro & Vrijenhoek (1989) (Q & V)

From: No bilateral asymmetry in wild-caught, endangered Poeciliopsis o. occidentalis(Gila topminnows)
