Sequence homology and differential expression. Histogram of sequence homology vs. count percentage for weakly biased (ratio less than 2-fold different), strongly biased (ratio greater than 2-fold different) and all biased genes in male vs. female comparison. Homology is defined as strong if bit score is 101 or greater, corresponding to an e-value of roughly 1 × 10-20; moderate if bit score is greater than 50, corresponding to an e-value of roughly 1 × 10-08; or weak if bit score is 50 or less.
