Synteny maps. Syntenic comparison of GAPD genes among human (Homo sapiens), stickleback (Gasterosteus aculeatus), zebrafish (Danio rerio), lancelet (Branchiostoma floridae) and sea squirt (Ciona savignyi). A) The locus containing GAPD-1 of human, GAPD-1 of stickleback, GAPD-3 of stickleback, the only GAPD isoenzyme of lancelet and one of GAPD isoenzymes of sea squirt. B) The locus containing GAPD-2 of human, GAPD-2 of stickleback and GAPD-2 of zebrafish. GAPD genes are shown by ovals, other genes - by rectangles. Homologues are indicated by discontinuous lines. The numbers near the yellow axes mean either the quantities of genes which are not shown or the distances in kilobases.
