Sentence examples for ancestral array from inspiring English sources

Fixed position of the variant 2* and truncation of variants indicate that arrays may be modified by consecutive deletions in the preexisting ancestral array.

The lineage loss time distribution for a given ρ is the following distribution of times: Given an array in stationarity, when does the last spacer from the ancestral array gets lost?

These are the ParaHox cluster (GSX1, PDX1, CDX2) on chromosome 13, and four sets of NKL-subclass genes on 2p/8p (split), 4p, 5q and 10q, hypothesized to be derived from an ancestral array by duplication [ 26, 33].

2. For each pair of spacers with overlap, generate the possible ancestors: Ancestral arrays can be arbitrarily large, but the probability of observing a certain length is given by p(n).

We propose a model in which the hominoid DUXY loci have most likely arisen by an evolutionary mechanism involving the transposition of an ancestral tandem array DUX gene cassette to the hominoid Y chromosome followed by lineage-specific chromosomal rearrangements that are rather common during speciation events.

We propose an evolutionary scenario in which an ancestral tandem array DUX gene cassette transposed to the hominoid Y chromosome followed by lineage-specific chromosomal rearrangements paved the way for a species-specific evolution of the Y-chromosomal members of a large highly diverged homeobox gene family.

While the final answer to the origin of Metazoa, the basal metazoan bauplan and (homeobox) gene content, might never be found [28], overall evidence is congruent with the view that an ancestral metazoan ANTP array harbored at least one ortholog each of Hox/ParaHox-like, NK, and extended Hox genes.

These new variants emerged sporadically during fish evolution in the main vertebrate lineages and likely originated during ancient rounds of genome duplications [ 80- 82] acting on polymorphic ancestral 5S rDNA arrays.

Figure 1a displays, in particular, the evolutionary pathway between #66 and #247, which descends through a nested array of ancestral haplotypes (marked in the figure by the corresponding haplogroup names) from the K1a1a type down to the root of haplogroup N and then ascends to the particular A2 haplotype.

In almost every case where the rDNA was lost from the ancestral site, the entire array disappeared without any other rearrangements in the region, leaving just an intergenic spacer of less than 2 kb.

Subsequent fusions and inter-chromosomal rearrangements further arrayed those ancestral clusters into 13 (i.e., A-M) basal proto-Actinopterygian linkage groups.
