Oct-11b, in contrast, does not have any of the introns we identified in Oct-11a and is therefore probably derived by retroposition.

A retroposition model has been proposed to account for the partial, and in some cases, complete, loss of editing in evolution.

RhoG belongs to the Rac subgroup and emerged as a consequence of retroposition in early vertebrates.

However, the technique requires very extensive genomic data - in the 2011 paper, approximately 200,000 retroposon-containing loci were examined to identify 51 individual retroposition events which are present in some birds but not others.

A classical event is the retroposition of a spliced pre-mRNA molecule of the c-src gene into the proviral ancestor of the Rous Sarcoma Virus (RSV).
