Summary of terms used in the three-locus population genetic model.

T2/T1	Allele for male attractive display trait/allele for unattractive display trait; lowercase denotes the respective allele frequencies
B2/B1	Allele for the male autonomy-enhancing trait/allele for the lack of the autonomy-enhancing trait
R2/R1	Allele for female preference for visiting males with the autonomy-enhancing trait (B2 males)/Allele for visiting males randomly with respect to males’ alleles at the B locus
s t	Viability cost to T2 males of producing an attractive display trait
s b	Viability cost to B2 males of producing the autonomy-enhancing trait
s r	Viability cost to R2 females of preferring males with the autonomy-enhancing trait (B2 males)
u	Mutation bias parameter: percent of the frequency of the T2 allele that mutates to the T1 allele each generation after mating and recombination
a t +1	Factor by which all females prefer to mate with T2 males
a b +1	Factor by which R2 females prefer to visit males with the autonomy-enhancing trait (B2 males)
c	Likelihood that a female gets coerced into mating without the opportunity to accept or reject a male based on his display upon visiting a male that lacks the autonomy-enhancing trait
γ	Effectiveness of the protection from coercion conferred by the autonomy-enhancing trait in B2 males
