Sentence examples for deviation from the ancestral from inspiring English sources
Comparing the nucleotide-level divergence among mammals with the extent of deviation from the ancestral base in the human lineage, we identify patterns of evolutionary pressure on nonsynonymous base-positions in groups of genes belonging to the same functional category.
The minor deviations from the ancestral gene partitioning pattern that we report for the Pedinophyceae and Trebouxiophyceae are consistent with the notion that these classes represent deeper branches than the Ulvophyceae and Chlorophyceae (Lemieux et al. 2014a).
Positional changes of genes from one side of the rRNA operon to the other appear to have been frequent during chlorophyte evolution, as they have been observed for other chloroplast genomes displaying slight deviations from the ancestral quadripartite structure (e.g. the cpDNA of Pyramimonas [ 25], Pedinomonas [ 46], and the trebouxiophyte Parachlorella [ 46].
The coefficient a indicates the deviation of the derived genetic state from the mean, while −a gives the deviation of the ancestral genetic state from the mean.
Moderate deviations from this ancestral-type architecture are seen in the two earliest-diverging lineages of the Ulvophyceae (the orders Oltmannsiellopsidales and Ulotrichales), supporting the hypothesis that a dozen genes were transferred from the LSC to the SSC region and that the rRNA operon in the IR was altered in orientation very early during the evolution of ulvophytes [ 3].
When the trend forms by competition, the ancestral form will persist and force selection in a single direction, away from the ancestral species.
These, as will be discussed in detail, originated by segregation from the ancestral insect compound eye.
Starting from the ancestral pattern, the ancestral B opsin duplicated in the lineage of Pieridae.
The Middle Eastern populations show contributions from the ancestral African population and the ancestral European population.
