Table 1.
Nucleotide variability of the fragment sequences of the 12S rRNA gene herein analyzed. Differences found in comparisons of the two fragment sequences (104 base-pairs long) produced by Sykes et al. (2014), and referred to in the text as focal sequences, with homologous fragments for Ursus arctos (49 individuals) and Ursus maritimus (32 individuals). The two focal sequences are identical to each other. The compared fragments correspond to positions 451–554 in complete sequences of gene 12S rRNA (using as reference GenBank sequence NC003428). Number of individuals is shown within parentheses.
