WebOct 13, 2014 · If the HCW was infected by any one of the patients, the observed diversity within the HCW is greater than would be expected to accumulate in the period from infection to observation. At least 16% of the observed HCW within-host pairwise distances would be rejected at the 5% level under any patient–HCW transmission scenario . WebDec 8, 2009 · These approaches have recently been named proportional diversity and differentiation diversity, respectively (Jurasinski et al., 2009), but this distinction is more formal than conceptual because traditional pairwise similarity indices are monotonic transformations of the multiplicative Whittaker's beta (i.e. gamma/alpha) computed for … WebMar 1, 1999 · Here, we report the application of the AFLP technique for estimating the nucleotide diversity (π), defined as the average number of pairwise nucleotide changes per site (Nei and Li 1979).

"Nucleotide diversity is a concept in molecular genetics which is used to measure the degree of polymorphism within a population. One commonly used measure of nucleotide diversity was first introduced by Nei and Li in 1979. This measure is defined as the average number of nucleotide differences per site between two DNA sequences in all possible pairs in the sample population, and is denoted by . " - Pairwise diversity
