ABSTRACT

The primary objective of the project was to determine the number of genetically distinct stocks of adult red sea urchins along the Pacific coast as indicated by possible variations in the DNA sequences of individuals sampled from six sites. The DNA results show that the binding gene of adult red seas urchins has a highly variable region and that the high allelic variation in this section exhibits a high non-synonymous:synonymous ratio. These results suggest that all adult red sea urchin populations along the Pacific coast are genetically distinct.
