Sentence examples for may have duplication from inspiring English sources
For some inserts, junctions will be found at both ends, but these are still indistinguishable from reciprocal translocations, especially since translocations may have duplication or deletion at the breakpoints [ 23].
Interestingly, there are two SR45 genes in rice (accessions AK070420 and AK063761) as opposed to one in Arabidopsis, indicating that SR45 may have undergone duplication after the divergence of monocots and dicots.
When multiple species are examined, some species may have both duplication products while other species may have only one representative.
Nine duplicated ECs are located less than 2Kbp apart from a retrotransposon and may have undergone duplication due to transposable element activity.
Large regions of a genome may have undergone duplication events resulting in the repetition of the pattern in tandem, one right after another.
Little is known about the nature of the biological mechanisms underpinning handedness/cerebral lateralization (although McManus 24, 43 speculated that it may have involved duplication and modification of mechanisms originally responsible for situs lateralization).
Cases of differential tandem duplication may have resulted from duplication in only one species or loss of duplicates from one species.
Some of those first-day requests may have been duplications as readers tried repeatedly to order.
The evolution of homologous genes during diversification of the populations they reside in (orthology) may have included duplications within (paralogy) and transfers between (xenology) those populations resulting in chimeric genomes with complex histories (Gogarten and Townsend 2005).
This separated tandem duplication may have arisen by recombination after duplication event, since duplications undergo high frequencies of recombination and are consequently unstable [ 25].
The order and timing of these duplications is still debated, as is their origin: for instance, αD may have evolved by duplication either of adult αA (see [ 12]), or of an embryonic α-like gene [ 14].
