WebAs for the analysis at the gene level, there was no statistically significant difference between autosomes and X once expression level was taken into account (model: log (ΣdN/ΣdS) ∼ Species + log (RPKM) + Chromosome Type, Chromosome effect F = 0.35, p = 0.55, figure 1 ). This result is confirmed by the fact that excluding X chromosomes from ...
