Cluster identification in chromosome 2. Automated cluster identification using the DBSCAN algorithm for genes in chromosome 2 outside the main known inversions. DBSCAN clusters are represented in color. Below each tSNE plot is a schematic representation of the chromosome and the starting points of each gene in a cluster is represented by a vertical line. Species F_ST computed between A. gambiae and A. coluzzii (red line), and general population F_ST (black line). “C” for centromere and “T” telomere. a Five clusters are found in the 2L chromosome (2L-i – 2L-v). b Seven clusters are found in the 2R chromosome (2Ri - 2Rvii). NA – gene not assigned to any cluster. Black arrows indicate key genes referenced in the text
