Sentence examples for evolution of a genome from inspiring English sources
During the evolution of a genome, those genes required for or that facilitate the survival of a species are created and maintained, whereas unwanted genes are discarded.
Thus, identification and annotation of SDs are important for understanding the structure and evolution of a genome.
To evaluate whether the gradients in expression and evolutionary rate predated the evolution of a genome with multiple chromosomes, we evaluated the relationships between replication timing, expression, and evolutionary rates in Bordetella, a close outgroup with a single chromosome.
In this regime, the two-allele genome model adequately describes the evolution of a genome with four nucleotides, because polymorphic sites with more than two nucleotides occur with negligible frequency.
This allowed us to assess the dynamics of evolution on a genome-wide scale using the P450 gene family.
Conservation across progenitor genomes indicated that the single base deletion in exon 1 that caused a pre-mature stop codon in TaHKT2 1 7and2 and TaHKT2 1 7AL-3 was an ancient event created during evolution of the A genome progenitor species prior to, and maintained during, polyploidization of the tetraploid and hexaploid genomes.
Finally, another interesting case of recurrent evolution of a genome-based sex determination system is the X-autosome balance in at least Drosophila and Caenorhabditis (reviewed in Haag 2005) and the plant genus Rumex (Navajas-Pérez et al. 2005).
Disease resistance gene clusters can comprise substantial portions of plant genomes, and understanding resistance gene clusters helps in the understanding of the structure and evolution of a plant genome as a whole.
We are naturally not in possession of the set of protein pairs that actually underwent duplication in the course of evolution of a given genome.
They faithfully report the evolution of a cancer genome, although they can sometimes be compatible with more than a single history.
More detailed description of the structure of homeologous linkage groups, with the addition of numerous additional loci, and sequencing of large BAC fragments mapping to these linkage groups, both in duplicated and apparently not duplicated regions, could be a useful step towards the understanding of the evolution of a tetraploidized genome.
