Multiple mechanisms promote the retained expression of gene duplicates in the tetraploid frog Xenopus laevis.

PLoS genetics - 1 Apr 2006

Chain Frédéric J J, Evans Ben J

Abstract excerpt

Gene duplication provides a window of opportunity for biological variants to persist under the protection of a co-expressed copy with similar or redundant function. Duplication catalyzes innovation (neofunctionalization), subfunction degeneration (subfunctionalization), and genetic buffering (redundancy), and the genetic survival of each paralog is triggered by mechanisms that add, compromise, or do not alter...
