The effect of topology on estimates of among-site rate variation.

Journal of molecular evolution - 1 Feb 1996

Sullivan J, Holsinger K E, Simon C

Abstract excerpt

Among-site rate variation, as quantified by the gamma-distribution shape parameter, a or alpha, and the ratio of transition rate to transversion rate (Ts/Tv) influence phylogenetic inference. We examine the effect of topology on estimates of these two parameters in 12S rRNA sequences from nine species of mice belonging to the genera Onychomys and Peromyscus by generating 100 random topologies and estimating these...
