Using a HMM to Identify Ectopic Gene Conversion Events
... The divergence time between duplicate genes is estimated using sequence divergence which can be greatly affected by the presence of gene conversions. An ectopic gene conversion event causes the sequence of one duplicate to overwrite the other, thereby removing any nucleotide sequence divergence pres ...
