Coalescent-Based DNA Barcoding: Multilocus Analysis and Robustness
DNA barcoding is the assignment of individuals to species using standardized mitochondrial sequences. Nuclear data are sometimes added to the mitochondrial data to increase power. A barcoding method for analysing mitochondrial and nuclear data is developed. It is a Bayesian method based on the coalescent model. Then this method is assessed using simulated and real data. It is found that adding ...
متن کاملSupplementary materials for Coalescent - based DNA barcoding : multilocus analysis and robustness
As we need to distinguish the gene of the test individual, samples of genes such as {x, yi} or yi are here considered as ordered. However we wish to relate P (x|yi) to probabilities of unordered samples as efficient methods have been developed to estimate such probabilities. Indeed samples are usually considered as unordered for statistical inference in population genetics since allelic multipl...
متن کاملMlcoalsim: Multilocus Coalescent Simulations
Coalescent theory is a powerful tool for population geneticists as well as molecular biologists interested in understanding the patterns and levels of DNA variation. Using coalescent Monte Carlo simulations it is possible to obtain the empirical distributions for a number of statistics across a wide range of evolutionary models; these distributions can be used to test evolutionary hypotheses us...
متن کاملMultilocus inference of species trees and DNA barcoding
The unprecedented amount of data resulting from next-generation sequencing has opened a new era in phylogenetic estimation. Although large datasets should, in theory, increase phylogenetic resolution, massive, multilocus datasets have uncovered a great deal of phylogenetic incongruence among different genomic regions, due both to stochastic error and to the action of different evolutionary proc...
متن کاملA preliminary framework for DNA barcoding, incorporating the multispecies coalescent.
The capacity to identify an unknown organism using the DNA sequence from a single gene has many applications. These include the development of biodiversity inventories ( Janzen et al. 2005), forensics (Meiklejohn et al. 2011), biosecurity (Armstrong and Ball 2005), and the identification of cryptic species (Smith et al. 2006). The popularity and widespread use (Teletchea 2010) of the DNA barcod...
