Hey all,

Quick question. When, for example, it's stated that for human exomes a Ti/Tv ratio of around 3.0 is expected, does that refer to the number of transitions divided by the number of transversions, or the number of transitions multiplied by 2 divided by the number of transversions (ie, absolute counts or rates)? I've been googling around and I think it's rates but I want to be absolutely sure that the commonly reported expected ratios refer to rates as well. Thanks for any help.
