GRANT ET AL.: POPULATION GENETICS OF YELLOWFIN SOLE 



Table 4. — Allelic frequencies of protein variants in samples of yellowfin sole of the 



correspond to location numbers in Table 1 



North Pacific Ocean and Bering Sea. Sample numbers

' Deviation from Castle-Hardy- Weinberg proportions, P < 0.01 . 



1 980, and 1 98 1 . One significant (P < 0.05) departure 

 from Castle-Hardy- Weinberg proportions was 

 detected for Gpi-1 in sample number 15 collected in 

 the Gulf of Alaska. 



Contingency-Table Analysis 



The results of the nested contingency-table 



analysis are presented in Table 5. Within the eastern 

 Bering Sea, the allelic frequencies of Gpi-1 and Pgd 

 for samples collected from 1975 to 1978 were not 

 significantly different from samples collected in 

 1979 from the same stock areas. Likewise, no signifi- 

 cant allele-frequency differences were detected for 

 Ada-2, Gpi-1, Pep-2, and Pgd for either the within- or 

 between-Bering Sea stock comparisons. Similarly,
