After exclusion of these regions encompassing recombination, and homoplastic sites (136 SNPs, identified by using PAUP 4.
2]) is also a homoplastic character that allows the recognition of the members of this clade (see Table 2); however, it is ambiguous concerning the optimization in the cladogram.
For the purposes of this paper, misleading characters (MCs) are defined as the fraction of all homoplastic characters and character states whose inclusion in a phylogenetic analysis may obscure the pattern of shared ancestry present in a data set and may lead to "strong" incongruence among data sets.
He successfully transplanted vessels using different methods--autoplastic, homoplastic and heteroplastic, using either fresh vessels or ones that he had preserved in cold storage for up to 3 months (Carrel 1912).
That distinct pattern of geographical distribution is important because, according to Sass & Specht (2010), the apparently homoplastic morphological characters used to assign species to genera or subgenera may be useful taxonomically when geography is also taken into account.
Dietrich and Deitz (1993) listed as synapomorphies for Cicadellidae: the mesonotum exposed posteriorly, the labium not reaching the metathoracic coxae, m-cul crossvein present, metatibia with distinct long setae, tarsomere I of hind leg without cucullate setae, stemum IX and subgenital plate not fused, and abdominal tergum with divided acanthae; all of which are homoplastic characters in their analysis.
For example, because the monocots represent an ancient group, there is certainly homoplastic noise in the sequence data due to nucleotide base reversals.
In terms of percentage of homoplastic characters, the amount of homoplasy in the behavioral characters is typical for phylogenetic datasets (Sanderson and Donoghue 1989; de Queiroz and Wimberger 1993).
Even for groups for which there is a good fossil record, the characters that are preserved may be homoplastic, or difficult to assess in terms of homology, leading to potential difficulties in accurate fossil placement.
Because previous genotyping data have demonstrated that homoplastic SNP mutations are virtually nonexistent in F.
Although the phylogeny of Compositae has recently been radically altered, the view that pollen characters are highly homoplastic continues to prevail.
It also may indicate that spine form is in some respects homoplastic.
