Sentence examples for been lost from either from inspiring English sources

Because so many contiguous genes are involved in this block of genes, and because almost all of the genes exhibit a similar direction and magnitude of deviation, we believe that this region has been lost from either one or both copies of chromosome 7 in the (presumably diploid) Lalvin isolate, yielding a net depletion in the copy numbers of these genes relative to the reference strain.
Finally, we note that while the catalase gene could have been lost from the Prochlorococcus lineage (either prior to or after the divergence from Synechococcus) as a consequence of neutral genetic drift, it may also have been lost as a selectively favorable event.

The non-amplification of sxtA1 and sxtA4 from the non-STX-producing species A. affine and A. andersoni may indicate that the sxtA genes have either been lost from these lineages or have mutated so much, that the primers developed here were not able to amplify them.
