Sentence examples for methods of ancestral from inspiring English sources

This chapter reviews phylogenetic methods of ancestral inference, strategies for investigating alternative reconstructions, gene synthesis, and design, and an application of these methods to the reconstruction of an ancestor in the green fluorescent protein family.

Our results therefore recommend against the adoption of ad hoc methods of ancestral state assignment.

Because alternative methods of character state reconstruction can produce conflicting results, both maximum parsimony (MP) and maximum likelihood ML methods of ancestral state reconstruction were employed [ 53, 54].

By applying phylogenetic methods of ancestral state reconstruction, we can reconstruct the probable points of origin on the eukaryote phylogeny of the various proteins.

Existing methods of ancestral sequence reconstruction can be divided into two main categories: Maximum Parsimony (MP) methods [ 1, 2] and Maximum Likelihood (ML) methods [ 3- 5].

The most widely used methods of ancestral area reconstruction that are able to take into account phylogenetic uncertainty and multistate characters are Fitch Parsimony (FP), implemented in the software Mesquite v. 2.7 [ 71] and Bayes-DIVA [ 72, 73].

Traditionally, vicariance and dispersal histories have been tested using phylogenetic approaches that use area cladograms [ 19, 20], consensus methods [ 21], or parsimony [ 22] in combination with some method of ancestral character state reconstruction.

This approach merges the maximum likelihood method of ancestral sequence reconstruction for substitutions, with the most parsimonious assignment of insertions and deletion to the branches of the phylogeny (Edwards and Shields 2004).

DupliPHY-ML has been updated to be more configurable, allowing the user to choose a specific optimizer, whether to fix or infer branch lengths, and to choose the method of ancestral reconstruction.

The combination of Bayesian divergence time information and a likelihood-based method of ancestral range estimation indicates that the formation of the geographic disjunctions observed today among the major notothenioid lineages closely followed the fragmentation of the landmasses encompassing the Weddellian Province.

However, denoting a site as ancestrally CpG based on the presence of a CpG in one of two extant species is clearly biased: this method of ancestral state assignment implies that misclassification of an ancestral non-CpG as CpG in two lineages requires only a single change whereas a minimum of two changes, one in each lineage, must occur to misclassify an ancestral non-CpG as CpG.
