Variations of snapshot population genetic indices with rates of
clonality and selfing, and ploidy
The principal component analysis on the values of genetic diversity
using a snapshot of genetic diversity of a population showed two main
non-collinear clusters of genetic indices associated with clonality and
selfing (Fig. S2, S3 and S4). Rates of clonality were colinear with
clonal heterogeneity and evenness indices (including R, Pareto Beta, the
complement of the Simpson index and Shannon-Wienner’s index), with
variance of Fis and Fit, and linkage disequilibrium. Increasing rates of
clonality increased linkage disequilibrium and variance of Fis among
genotyped loci while it decreased clonal evenness. Rates of selfing were
colinear with indices based on allele diversity (including gene
diversity, probabilities of identity and genetic structure indices) and
heterozygosity. Increasing rates of selfing increased mean Fis and Fit,
and variances of panmictic probabilities of identity, of the number of
alleles per loci, of gene diversity and of pairwise Fst. Conversely, it
decreased the mean number of alleles per loci, the mean gene diversity
and observed heterozygosity.
The distributions of population genetics indices varied with joint rates
of clonality and selfing and with increasing ploidy, except the
distribution of rhost values between the two simulated populations (Fig.
S5). For a fixed ploidy, changes in the range of expected values with
reproductive modes remained quite similar to those observed for
diploids.
