Incomplete Lineage Sorting and Hybridization Statistics for Large-Scale Retroposon Insertion Data
Fig 1
Possible discrepancy between one- and two-sided (species) screenings.
Screening for phylogenetic markers based on all possible tree topologies for three species A, B, C when only one reference genome A (a-c) or B (d-f) is available. The red lineage indicates the branches where markers can be detected. Screening from A reveals three markers. The two light red markers are artifacts from ancient incomplete lineage sorting (ILS) and the dark red marker is a phylogenetically informative marker. Screening from B reveals 11 markers with 8 markers supporting B plus C and one marker supporting A plus (B plus C). The two light red markers in (d) are the same detected from species A in (a). The correct topology is shown in tree (f). This correct tree would not be detectible by screening only from the genome of species A.
