Assessment of phylogenetic approaches to study the timing of recombination cessation on sex chromosomes
The evolution of sex chromosomes is hypothesized to be punctuated by consecutive recombination cessation events, forming “evolutionary strata” that ceased to recombine at different time points. The demarcation of evolutionary strata is often assessed by estimates of the timing of recombination cessation (tRC) along the sex chromosomes, commonly inferred from the level of synonymous divergence or w
