NOTE.—Testis expr, whether or not the gene is testis expressed; sex-bias, whether the gene has female-biased expression (F), male-biased expression (M), or no significant sex-biased expression (NA). A, autosome; X, ancestral X chromosome; neo-X, neo-X chromosome; arrows indicate direction of relocation.
