Table 3. Percentage of genomes from each country for which the extended coding sequence of a given gene was 100% identical to the most common extended coding sequence.

	mpb70	mpb83	sigK	rskA
United Kingdom	94.1%	88.2%	94.1%	94.1%
United States	76.0%	80.1%	93.7%	93.2%
Mexico	89.9%	89.9%	97.3%	96.2%
Overall	83.1%	84.9%	95.2%	94.5%

The overall percentages are not simply the average of the other three percentages, but rather are weighted averages that take into account the number of sequences from each region.
