Molecular phenotyping of maternally mediated parallel adaptive divergence within Rana arvalis and Rana temporaria.

abstract：:DNA-based sex tests now exist for many avian species. However, none of these tests are widely applicable to ratites. We present DNA sequence data for a locus that is W chromosome-linked in the kiwi, ostrich, cassowary, rhea, and emu. At the amino acid level, this sequence has significant homology to X-linked genes in ...
