Positive correlation between evolutionary rate and recombination rate in Drosophila genes with male-biased expression.

abstract：:Most phylogenetic models assume that the evolutionary process is stationary and reversible. In addition to being biologically improbable, these assumptions also impair inference by generating models under which the likelihood does not depend on the position of the root. Consequently, the root of the tree cannot be inf...

Why many histone modifications can be stably maintained in the midst of genetic and environmental changes is a fundamental question in evolutionary biology.
