We argue that the vertebrate vtg gene cluster originated in proto-chromosome m, but that vtg genes have subsequently duplicated and rearranged following whole genome duplications.
This process requires neither germ-line expression nor the evolution of de novo cis-regulatory sequences as does retrotransposition (Zhang 2003) and, if repeated so that the resulting pairs or larger clusters of genes were subsequently duplicated in the same manner, a relatively small number of duplication events could give rise to a large number of duplicate genes.
The other gene was lost from rice and the remaining rice gene was subsequently duplicated.
Once integrated, the retroviral genome becomes a stable part of the host genome, and is subsequently duplicated as a provirus during host cell division.
This ancestor gene subsequently duplicated differently in the different vertebrates lineages and resulted in 2 to 5 genes, depending on the species [4].
It was proposed that a single ancestor gene, currently conserved from fruit fly to jellyfish to tunicates, was first duplicated to produce the ancestor genes to MyoD/Myf5 and Mrf4/Myog which subsequently duplicated again, resulting in the current MRFs [4], [5].

Subsequently, duplicate reads were removed using samtools (version 0.1.19), and only those with non-zero mapping quality and no suboptimal alignments were considered further.
Subsequently vtgA duplicated and formed paragolous vtgAa and vtgAb genes in acanthomorph teleosts.
Unless new evidences emerge from future updates in the sequenced genomes, we hold true that these genes have newly evolved, probably from modifications on previously non-coding ancestral DNA sequences and subsequently disperse duplicated.
Phylogenetic reconstruction of the evolutionary history of the PE and PPE gene families suggests that the first pair of these genes were initially inserted into the ESAT-6 (esx) gene cluster region 1, and have subsequently been duplicated along with the regions.
Subsequently this segment duplicated, with transposition of the daughter locus to the telomeric region.
Write better and faster with AI suggestions while staying true to your unique style.
Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
