A sliding window of the likelihood ratio that the selective sweep has acted on a particular region of the sequence. Window length was set to 20 bp. The position of the missing GATA-1 box, the conserved regions including middle region1, and deletion D1 (not present in this alignment, see text) is indicated. Arrows indicate the possible locations of the mutations that rendered COb a pseudogene.
