Testing for Gene Conversion in the Post-Speciation Duplicated Blocks.

*The presence of evidence for gene conversion in the D. melanogaster and D. simulans (D. sechellia) based on the tree shape analysis. The regions for which an outgroup sequence is available are analyzed. ��yes�� and ��no�� represent the presence and absence of evidence.L��: the number of nucleotides used in the statistical analysis of the four sequence-alignments.j and k: the numbers of type-N and type-C sites, respectively. k�� is the expectation of k (see text, especially Methods for details).
