Comparison of methodological approaches to the study of young sex chromosomes: A case study in Poecilia.

ABSTRACT: Studies of sex chromosome systems at early stages of divergence are key to understanding the initial process and underlying causes of recombination suppression. However, identifying signatures of divergence in homomorphic sex chromosomes can be challenging due to high levels of sequence similarity between the X and the Y. Variations in methodological precision and underlying data can make all the difference between detecting subtle divergence patterns or missing them entirely. Recent efforts to test for X-Y sequence differentiation in the guppy have led to contradictory results. Here, we apply different analytical methodologies to the same data set to test for the accuracy of different approaches in identifying patterns of sex chromosome divergence in the guppy. Our comparative analysis re
