Sentence examples for mutations or recombination from inspiring English sources

He believes the emergence of a pandemic virus in a human host--through mutations or recombination with a human flu virus--is and will remain a very rare event.

We hypothesized that this is, at least partially, due to newly occurring mutations or recombination of favorable alleles in the selected population.

The phylogeny model assumes that there are no recurrent mutations or recombination within each short sequence region.

Mutations or recombination events that occur between individuals that do not contribute to future generations are not simulated.

This is consistent with the idea that the evolution of R genes is driven by selection of allelic variations created by mutations or recombination within these clusters.

GII.4 NoV strains continuously undergo genetic/antigenic diversification and periodically generate novel strains through accumulation of punctate mutations or recombination.

Nevertheless, genetic mutations or recombinations in the HA of an influenza virus can render interspecies transmission by altering the receptor tropism [27], [28], [29].

The GII.4 norovirus strains undergo continuous processes of genetic/antigenic diversification and periodically generate novel strains through the accumulation of punctuate mutations or recombinations, and novel GII.4 variants emerge every 2 3 years [ 21, 22].

The durability of the resistance depends on the time taken for new mutations or recombinations to generate the matching combination of virulence factors in the pathogen population and for that pathotype to establish itself in the population.

Within complexes, mutant profiles were discriminated from recombinant profiles (and associated alleles) by assessing whether SHVs diverged by mutation or recombination.

The variants that arise by mutation or recombination are not transmitted equally from one generation to another.
