Immune genes and their distribution over autosomal and sex chromosomes. Immune genes were obtained because of either a 4-fold elevated expression in lymphoid tissues (LTEEG) or the annotation for immune system process (GO:0002376). Chromosomes are ordered by rank based on their absolute number of LTEEG (a) or GO genes (b). Likewise, chromosomes were ordered according to their normalised contribution index to LTEEG (c) and GO genes (d). The normalised contribution index of each chromosome is calculated as follows: %LTEEGchr/%PEGchr , with %LTEEGchr is the proportional contribution of the chromosome to all LTEEG and %PEGchr is the proportional contribution of the chromosome to all protein-expressed genes (PEG). The dashed line at “1” indicates that a chromosome has the same relative contribution to LTEEG as to PEG
