Genetic variation and population homogeneity of the sea star Coscinasterias tenuispina (Forcipulatida: Asteroidea) on the coast of Rio de Janeiro, Brazil

Genetic variation and population homogeneity of the sea star Coscinasterias tenuispina (Forcipulatida: Asteroidea) on the coast of Rio de Janeiro, Brazil

ABSTRACT Genetic variation and population structure of the sea star Coscinasterias tenuispina were investigated using allozyme electrophoresis (seven polymorphic loci out of nine sampled) at seven sites on the coast of Rio de Janeiro State. Observed values of heterozygosity's were high (HOBS =...
