This proliferation may be attributed to the duplication of individual genes, or even the entire genome.
The unusually low susceptibility of E. faecium in our study may be attributed to specimen duplication.
In particular, most of the variation was due to gene losses or to nucleotide divergence (Log2-ratio > 0), while a smaller fraction of the variation could be attributed to gene duplication (Log2-ratio < 0).
Although much of the extraordinary diversity of the pan-fungal CYPome can be attributed to gene duplication and adaptive divergence, our analysis also suggests a few potential horizontal gene transfer events.
We determined that there was no difference in the distortion rate between male and female offspring in the region of suggestive paternal-specific TD on chromosome 6p (P = 0.5379), and therefore this signal cannot be attributed to a duplication or paralog on a sex chromosome.
The origin of tandem peptide repeats can be attributed to intragenic duplication and recombination [ 28], which could explain the differences in number but also the similarity in the repeats within a protein and within a genus and family, as discussed below.
Therefore, some of the observed most recent gene duplications on different chromosomes in Arabidopsis and rice genomes may be attributed to segmental duplications.
Estimates for the incidence of polyploidy in angiosperms vary from 30 to 80%, and 2 4% of speciation events can be attributed to genome duplications (Otto and Whitton 2000).
Previous studies showed that the evolutionary emergence of BORIS in amniotes occurred before the divergence of reptiles and mammals and could be attributed to an initial duplication of the entire CTCF sequence [18].
Although in C. arietinum the large number of T2-RNase lineage genes can be attributed to recent gene duplications, most of the T. pratense, and M. truncatula gene duplications are old.
