Sentence examples for ancestral units from inspiring English sources

Evolving from ancestral units, organisms of different kinds lived together until they periodically or permanently merged and covered themselves with exudates, skins, sheaths, or coats made by both partners.

On the basis of the phylogenetic tree, we deduced the hypothetical origins of 23 genes from two ancestral units by tandem duplication (Supplementary Fig. S5B).

To determine the degrees of expansion of these two classes among monocot and dicot plant lineages, we broke down the phylogeny into ancestral units according to the method.

The 19 tandem genes are in three clades, suggesting that this cluster was the results of three ancestral units, which may be evolved from ancient tandem duplication events.

The phylogenetic tree was then broken down into ancestral units, which were clades that were present before the divergence of these organisms according to the method described by Shiu et al (2004) [ 68].

We found that there were 9 ancestral units among 105 soybean and 38 Arabidopsis B-lectin members; however, only 5 MRCAs have been detected among total of 230 B-lectin family members from these three organisms.

For the ancestral unit with 3 descendents, only two rounds of tandem duplications were required to generate these genes.

A character state change (point mutation, insertion or deletion), defined as a triad of the ancestral sequence unit, unit position and the derived sequence unit is called a marker.

These ancestral SHORT1 units may have been more similar to MSHORT1 than to RSHORT1.

Many of the characteristics are strikingly similar to those found in the trunk segments, opening the debate on whether the pygidium and trunk segments derive from the same ancestral metameric unit.

In this scenario, an ancestral 35S-5S unit may have undergone a series of deletion and mutation events in intergenic spacers, perhaps inactivating transposon activity, while selection has apparently acted to maintain coding regions.
