Trichotomy
Definition:
(n.) Division into three parts.
Example Sentences:
(1) The quantitative changes that occurred in the dendritic trees of these cells (increase in segment length, decrease in segment numbers, trichotomy and branching probability) were similar to those seen following other degranulation procedures.
(2) Nevertheless, trichotomy was uniformly reduced in those trees without 'giant spines' and the distribution of branching patterns suggested that growth had proceeded by random terminal dichotomy.
(3) Using the Brief Psychiatric Rating Scale (BPRS) as a clinical example, we cover the principles of expressing scale reliability in terms of a dichotomy ("absence" - "presence" of a given BPRS symptom); as a trichotomy ("none"; "mild to moderate" symptomatology; and "severe" symptomatology); and as the full 7-category dichotomous-ordinal scale: "none," "very mild," "mild," "moderate," "moderately severe," "severe," and "extremely severe."
(4) Except in the case of the tree generated from reciprocal-corrected delta Tm data, nodes were stable under jackknifing; and, again excepting the above-mentioned trichotomy, all nodes were supported by 95% or more of the bootstrapped trees.
(5) A deep trichotomy is thus observed within the ciliates.
(6) In addition, the 2DE data set appears to resolve the human-chimpanzee-gorilla trichotomy in favor of a more recent association of chimpanzees and humans.
(7) The above results, together with changes in segment length, trichotomy, branching probability, and growth cone morphology during development have been discussed in relation to current concepts of dendritic growth.
(8) The quantitative changes in segment lengths, size of trees, and trichotomy accord with those predicted by the filopodial synaptogenic hypothesis of dendritic growth formulated by Vaughn et al.
(9) It was discussed that functional trichotomy of retinal ganglion cells is related to the differentiation more in axon diameter rather than in soma size.
(10) Estimates of gene frequency and displacement from a phenotypic trichotomy agree closely with conventional values for the the dichotomy of tasters vs. nontasters.
(11) They were often some 10 mum in length and their presence effectively reduced segment lengths, increased the frequency of trichotomy and deviated growth from the normal random terminal pattern so that long collateral branching topologies were formed.
(12) Comparisons of cytochrome oxidase subunit II gene sequences provide clear-cut evidence from the mitochondrial genome for the separation of the African ape trichotomy into two evolutionary lineages, one leading to gorillas and the other to humans and chimpanzees.

(14) In spite of the presence of the complete sequence data of mitochondrial genomes, we could not resolve the trichotomy among human, bovine and murids, probably because the time length separating two branching events among these three lines was short and because chicken is too distant from mammals to be used as an outgroup.
