Specifically, what is a reasonable point estimate or distribution for the Ts:Tv ratio for plant nuclear DNA, 1) in general, 2) for conifers, and 3) more specifically for Pinaceae? I am looking through the literature for a value, or range of values, to use during simulations of DNA alignments in a study of pine trees. However, I would like to keep any information that the community can provide on this, for future reference during simulations or setting priors during Bayesian phylogenetic inference. A comparison of reasonable chloroplast vs. nuclear values would also be useful. Thanks ~J
