A) The black and green lines represent nonallelic loci, the
yellow arrowheads represent a repeated sequence and the blue box represents a
gene. A DNA DSB in the green locus is repaired by copying sequence from the
black locus, including the blue gene. The recombination event was seeded by
homology shared between the yellow arrows. B) The blue boxes
represent members of a gene family. Over time, the red variant can spread to all
members of the blue gene family via gene conversion. C) The blue,
red, and light blue boxes represent diverged members of a gene family. Over
time, gene conversion can shuffle the variation between members of the family to
generate novel alleles.
