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.
