Total size of significantly differentiated regions (SDRs) in base pairs along different chromosome segments.

*Total proportion of significantly differentiated regions in relation to the total A. gambiae genome size ( = 273 Mbp) **The remaining genes 827 ( = 13,254–12,427) belong to UNKN segment, a large segment that has not mapped to chromosome.显著分化区域占冈比亚按蚊（Anopheles gambiae）总基因组大小（即273 Mbp）的总占比。剩余的827个基因（数值范围为13254至12427）属于UNKN片段（UNKN segment），该片段为未定位至染色体的大片段区域。
