This is clear evidence of allelic homoplasy in the marker that could confound interpretation of data sets.
tree length, CI and RI) indicated more synapomorphic value and less homoplasy when urogenital duct characters were optimized to a phylogeny with a monophyletic Salamandroidea.

Because the chloroplast genomes of plants that no longer carry on photosynthesis are subject to reduced selection pressures, their mutation rates are often elevated which can lead to homoplasy and misleading phylogenies (Felsenstein, 1978; Nickrent and Star, 1994; dePamphilis, 1995; Nickrent and Duff, 1996, 1996; Nickrent et al.
Wood and Harrison argued that it is naive to assume that all fossils are the ancestors of creatures alive today and also noted that shared morphology or homoplasy - the same characteristics seen in species of different ancestry - was not taken into account by the scientists who found and described the fossils.
For Rosseto (2001), similar PCR products should be carefully compared, since several factors can lead to homoplasy.
As a sequencing-based method for a single locus, spa typing possesses moderate discriminatory power, between PFGE and MLST; however, repeat-based spa typing is subject to misclassification bias due both to horizontal DNA transfer and to recombination and homoplasy (16).
They found rampant homoplasy, but noted that closely related compounds (pairs of phenols and quinones) could easily be transformed into one another by oxidation or reduction, suggesting that "families" of such compounds could represent synapomorphies as transformation series of compound families.

The second synapomorphy, which is homoplasy free within the fishes examined, concerns the presence of a 'leptocephalus larva' (see char.
