Sentence examples for ambiguous tree from inspiring English sources

This comparative genomic approach is particularly powerful to infer the duplication history of gene families in case of ambiguous tree topologies as well as species-specific gene order rearrangements or genome assembly problems (Braasch et al. 2008).

Phylogenetic analysis of the remaining two genes yields an ambiguous tree topology for bioA and indicates that bioB may be derived from a single evolutionary acquisition that preceded the diversification of whiteflies (superfamily Aleyrodoidea) and mealybugs (members of the superfamily Coccoidea) (supplementary fig. S3, Supplementary Material online).

Not surprisingly, a number of phylogenetic studies from molecular and morphological data have resulted in ambiguous trees and relationships amongst species, especially for Yak and Bison species.
