These 2D topologies contain both anchor points ('registration marks' in the image processing literature) and the user's empirical amplicon sequences, with distances in the plane approximating distances between the underlying sequences.
The potential for issues with disagreement between fragment size and underlying sequence has been known for some time (Doyle et al., 1998; Provan et al., 2001; Navascués and Emerson, 2005), but still relatively few papers reported investigating size homoplasy in their data sets.
First, DNA methylation patterns are better correlated with histone methylation patterns than with the underlying genome sequence context.
Given the potential for fragment size homoplasy to occur between and within species, we recommend that all studies making use of cpSSRs perform some sequencing of alleles to verify the mutational patterns of underlying sequences.
The Upper Cretaceous Gongila Formation in the Chad Bornuu) Basin, northeastern Nigeria has always been considered as a transitional sequence between the underlying continental Bima Formation and the overlying marine Fika Formation.
This package is tectonically interposed between the underlying, low-grade, Lesser Himalaya sequences and the overlying, high-grade and locally anatectic, Higher Himalayan Crystallines (HHC).
"But there is a huge disconnect between the underlying economy and the confidence of investors".
Although the phylogenetic tree adjusts for the underlying evolutionary relationships between HIV sequences, immune selection pressures may lead to reproducible patterns of mutations at linked sites, even in sequences located far apart in the tree.
Comparison of the repetition of genomic sub-sequences of ssRNA length between Arabidopsis and E.coli suggest that the network structure is made possible by the underlying repetitiveness in the genome sequence.
The variation in an OTU can come from sequence differences between closely related taxa in the underlying population, through errors introduced into the amplified fragment from the PCR amplification, or from DNA sequencing errors.
