The relationship between $F_{ST}^k$ (Eq. 14), which partitions the variance of allelic indicator variables representing a single copy of each locus, and $F_{ST(\ell )}^k$ (Eq. 16), which partitions the variance of sums of ℓ allelic indicator variables at each locus. Thus, for haploids (ℓ = 1), $F_{ST(\ell )}^k=F_{ST}^k$. For higher ploidy, $F_{ST(\ell )}^k\in \left[F_{ST}^k,\ell F_{ST}^k\right)$, with $F_{ST(\ell )}^k=F_{ST}^k$ if and only if $F_{ST}^k=0$ or $F_{ST}^k=1$ (see Appendix 1). The plot is obtained from Eq. A1.4.
