TABLE 1.

Notation

i, j, k	Indices for loci; j and k are selected loci, and i modifies the recombination rate between j and k
pl, ql = 1 − pl	Frequency of allele 1 (pl) and of allele 0 (ql) at locus l
Xl, Xl*	Indicator variables that equal 1 if allele 1 is present at locus l on the maternally inherited chromosome (Xl)   or paternally inherited chromosome Xl* of a given individual and 0 otherwise
ζl = Xl − pl	Scaled indicator variable
ζU	Product of ζ-variables over the set of loci U
CU, CUH	Genetic association between loci in the set U during the haploid phase (in the gametophytic selfing model),   before and after haploid selection
CU,VS, CU,VD	Genetic association between loci in the sets U and V on homologous chromosomes of diploid individuals,   before and after diploid selection (in the sporophytic selfing model, CU,VS is noted CU,V)
aUH, eUH	Effect of haploid selection acting on the set of loci U (in the gametophytic selfing model) and epistasis between   these loci on a multiplicative scale
aU,VD, eU,VD	Effect of diploid selection acting on the sets of loci U and V present on homologous chromosomes and epistasis   between these loci on a multiplicative scale; D superscripts are dropped in the sporophytic selfing model
s	Direct selection acting on loci j and k, under the fitness matrix given by Table 2
h	Dominance of alleles 1 at loci j and k, under the fitness matrix given by Table 2
ea×a, ea×d, ed×d	Additive × additive, additive × dominance, and dominance × dominance epistasis between loci j and k, under   the fitness matrix given by Table 2
α	Rate of self-fertilization (either gametophytic or sporophytic)
rij, rjk	Recombination rate between loci i and j and between loci j and k (without modifier)
dr	Effect of the modifier on rjk
hM	Dominance of allele 1 at the modifier locus (locus i)
tS,T	Probability that a gamete produced by an individual contains the set S of loci derived from one of its parents   and the set T from the other
S,T	Population average of tS,T
δtS,T|i, δtS,T|i,i	Additive effect of the modifier on tS,T and effect of dominance at the modifier locus
ε	Scaling factor
