Teeth and bones as sources of DNA for genetic diversity and sex identification of Commerson's dolphins (Cephalorhynchus commersonii) from Tierra del Fuego, Argentina

Museum specimens are often the only source of genetic material for many species of cetaceans. Most of the protocols that have been developed to extract DNA from teeth and bone samples involve mechanical or chemical disintegration of the material. An alternative method to the mechanical reduction pro...

description Museum specimens are often the only source of genetic material for many species of cetaceans. Most of the protocols that have been developed to extract DNA from teeth and bone samples involve mechanical or chemical disintegration of the material.

From the total samples, 82.5% (n = 175) allow for amplification to occur of a minimum length of 200 pb for the mtDNA control region, 66.5% (n = 141) of 400 bp, and 51% (n = 108) of 500 bp.
