Example of the data matrix generated for each family based on transposon display data (Tc1NA2.1 shown here). Each row represents one lineage (sexuals in light gray, asexuals in white). Each column represents a locus occupied in the ancestor (numbers indicate size of fragment produced by transposon display) and dark gray columns represent high loss loci (losses observed in more than three lineages at a given locus).
