Duplication and loss of phototransduction gene-family members in our dataset. Duplications (bold, black background) and losses (italics, white background) were mapped onto a consensus species tree [79,104,109]. Reconciliation of gene trees onto the species tree was performed with Notung using Maximum Likelihood gene family trees (see Methods).
