Sentence examples for low rate of variation from inspiring English sources
Matrix and polymerase viral genes, which show a low rate of variation, were chosen to design amplification assays to ensure that any genotype of the human metapneumovirus could be detected.
From the explanation given regarding these five SCs, we can conclude that the SCs with a low rate of variation do not result in a change in the power of the first detail, which is found in the frequency band 41.67 83 mHz.
As well, homoplasy is unlikely, given the low rate of variation of angiosperm and conifer mitochondrial introns [ 47, 49].
