A few theoretical works have modelled the loss of functional genes underlying sex chromosome degeneration. Yet only recently have empirical studies begun to provide substantial evidence that evaluate the model predictions. Furthermore, the sequential dynamics of degeneration remains largely unknown, such as accumulation of transposable elements, reduced gene expression efficiency, accelerated evolutionary rate, accumulation of stop codons and frame-shift mutations. We aim to address dynamics of the degeneration processes and quantify each form of degeneration in a systematic frame across sex chromosomes with various evolutionary stages.
