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