Table 1 Notation General remarks

From: Reinforcement of genetic coherence in a two-locus model

A modifying locus with two alleles A1 and A2
B object locus with two alleles B1 and B2
two-locus gamete (A i B k ) with allele i at the A- and allele k at the
  B-locus
zygote or any other diploid genotype originating from fusion of ga-
  metes (A i B k ) and (A j B l ). Note that because of unordered geno-
  types but because of linkage
a i , b k relative frequencies of alleles A i , B k among adults
relative frequency of gamete in the gametic production
relative frequency of genotype among adults
a ij , b kl relative frequency of genotype A i A j and B k B l , respectively, among
  adults
r recombination frequency (0 ≤ r ≤ ½)
probability of fusion when the gametes and encounter.
  f-values are assumed to differ in only three ways:
  f2 := probability of fusion in the presence of allele A2 in at least
  one of the two encountering gametes, for all i, k, l;
  := probability of fusion when A1-carriers with equal B-alleles
  encounter (homotypic mating), ;
  := fusion probability among A1-carriers with different B-
  alleles (heterotypic mating), ;
v kl viabilities at the B-locus
combined selection value of fusion probability and viability selection,
  defined as
  1. The designation of gene loci, alleles, gametes, and genotypes is by uppercase letters, relative frequencies and probabilities are indicated by lowercase letters. The indexing for two-locus-types is done such that A- and B-locus alleles appear as subscripts and superscripts, respectively. The indices appearing one upon the other indicate alleles located on the same gamete prior to or at fusion. A prime indicates next generation frequencies.
