Comparisons of Mitochondrial DNA in Black and White Rhinoceroses

Mitochondrial DNA restriction maps of Diceros bicornis, the black rhinoceros, and Ceratotherium simum, the white rhinoceros, were constructed to provide a basis for population genetic and systematic studies. The sequence divergence between DNA of the two species was calculated to be 6.79% from which...

Description
Summary:Mitochondrial DNA restriction maps of Diceros bicornis, the black rhinoceros, and Ceratotherium simum, the white rhinoceros, were constructed to provide a basis for population genetic and systematic studies. The sequence divergence between DNA of the two species was calculated to be 6.79% from which it could be estimated that the time of divergence from a common ancestor was ca. 3.4× 106 years ago. Little intraspecific variation was found in the 24 black rhinoceroses or the 4 white rhinoceroses studied.
