Positional conservation along OR sequences. Positions above the horizontal line are such that exceed the conservation score threshold (P < 0.05 of chi square and FDR correction) for orthologous pairs (75 positions, Pink) and for paralogous pairs (96 positions, Blue). The overlapping conservation core set includes 65 positions. The conservation scores are normalized per the statistical significance threshold for each of the two sets.
