  1. a Veis the expected variance if the alleles present at different loci in a strain are independent (i.e. no linkage disequilibrium), Vo is the observed variance.
  2. b Standardised IA [26] calculated using LIAN3.1. P = probability of observing a Vo/Ve ratio equal or more extreme to that found in the original data based on 1,000 Monte Carlo randomisations.
