NOTE Gryalva-Chon et al.: Allozyme variability in Xiphias gladius 



591 



for 1 to 1.5 years at -70°C before analysis. Because 

 of this, IDH was eliminated from the analysis. 



Only one locus was out of Hardy- Weinberg equi- 

 librium: GPI-1* showed heterozygote deficiency in 



the Mexican sample (Table 3). This result was re- 

 flected in the F is value for that locus (Table 4). The 

 genetic distance between populations was very low: 

 it varied between 0.000 and 0.014, with a mean of 

 0.0007 over all loci.
