Evolution of Gene Families

Zebrafish are members of the teleosts (ray-finned fishes) that constitute more than half of all extant vertebrate species. This remarkable radiation was likely helped by a whole genome duplication event that occurred at the base of the lineage. Functional redundancy of duplicated genes paves the way for interesting functional divergence, leading to experimental conditions where cell type specific genetic manipulations become feasible.

This favorable evolutionary scenario also has important ramification for the evolution of gene families. We use bioinformatic approaches to build phylogenies of selected gene families to achieve correct gene annotations and get insight into their evolution.
