Sentence examples for speciation type from inspiring English sources

We compared K, dS and dN mean ratios between paralogs, except for genes E and I, which present a topology of "duplication before speciation" type.

The example of Figure 1 does not satisfy this property, as { (a ), ((a, f ), (g, h ) ) } is a join of duplication type (AD), { ((a, f ), (g, h ) ), (g ) } is a join of duplication type but { (a ), (g ) } is a join of speciation type.

If these coefficients are superior to 1, it means that some amino acids were subject to altered selective constraints (type I functional divergence) or that a radical shift of amino acids physicochemical properties occurred after gene duplication and/or speciation (type II functional divergence) [ 50- 53].

Overall, sequences B and D clearly show a "duplication after speciation" topology type.

The initial MDR-Aci isolate from each patient was sent to the Laboratory of HealthCare Associated Infection in Colindale, London for speciation and typing by pulsed-field gel electrophoresis (PFGE) and other molecular methods [ 10].

A total of 151 isolates from culture positive sputum samples were harvested, heat killed at 80°C for two hours, and then shipped to Makerere University College of Health Sciences, Uganda, for speciation and typing.

Moreover, the speciation between CD-type and TAD-CD-type kinases from the same organism (e.g., Geobacter sp. M18 and Desulfobacca acetoxidans DSM) suggests that CDs of each BY-kinase type have different evolutionary histories, even in the same organism.

However the speciation and sequence type of these clinical isolates has not been published.

In this type of speciation, called geographic speciation or allopatric speciation, reproductive isolation may be achieved by prezygotic or postzygotic barriers (reviewed in [1]).

Using NOTUNG reconciliation every node in each tree was assigned to one of two types: speciation or duplication and every edge and every leaf (extant gene) to one of three gene types – paralogs, true singletons and remaining paralog from a lost duplication.

Researchers have previously proposed that differences in vocalizations can be a driving force behind speciation in other types of animals, including songbirds with overlapping ranges (ScienceNOW, 20 August 2003 ), but Kingston says the new study is the first evidence of such a mechanism in mammals.
