Chow et al.: PCR-RFLP analysis on thirteen western Atlantic snappers 



625 



Lutjanus and Ocyurus ranged from 0.7 to 3.07 with an 

 average of 1.21, for those between Lutjanus and 

 Rhomboplites it ranged from 1.24 to 2.81 with an 

 average of 2.16, and for that between Ocyurus and 

 Rhomboplites it was 2.41. Nucleon diversity estimates 

 (/; ) within species ranged from to 83.3%. 



Discussion 



Eight out of thirteen western Atlantic snapper species 

 examined may be identified by PCR-RFLP analysis of 

 the two mitochondrial genes, although further analy- 

 sis for the intraspecific polymorphism is neccessary for
