Overall the measured differences between siblings are a small fraction of that determined among the accessions; over repeated generations, however, drift in the copy number of these elements could contribute to large differences.
However, in Berytidae, no copy of this spacer was found across the mt-genomes.
However, in 2006 a copy of a very early test engine was sold at auction to an anonymous collector who bought it for US$2500.
In plant genomes, however, the copy numbers of both putative endogenous retroviruses like SIRE1 [ 11], Calypso[ 10], and BAGY-2 [ 13] and retrotransposons like BARE-1 [ 42], Opie-2 [ 21], and Diaspora reach into the thousands.
However, in biological sequences, copies of the repeated patterns may change gradually so that some repeats in the region may have very little in common.
However, the copy number of the elements in the tomato euchromatic regions may have been reduced due to the purifying selection, which could have resulted in the lower accumulation of the LTR retrotransposons in the tomato euchromatic regions than in those of pepper.
However, the copy number of these variants differs in different samples.
However, the copy numbers of 16S rRNA gene in prokaryotic microorganisms are not equal and may vary from 1 to 15 (Klappenbach et al. 2001).
It is not tradition, however, in the sense of uncritical reiteration, or unimaginative copying.
In the case of NCX1, this difference may be related to the duplicate copies of NCX 1, however in the case of NCX3, fish did not retain the duplicated NCX3 gene [ 38].
