From: Phenotypic plasticity promotes recombination and gene clustering in periodic environments

Symbol

Description

p

Plasticity effect—a constant that quantifies the amount of buffering of environmental effects due to the plasticity allele

s max

The maximum environmental effect, occurring at a peak season in those individuals who do not carry the plasticity allele

C

The number of discrete generations in one oscillating cycle of periodic environmental change

M

The plasticity-conferring allele at the modifier locus, as opposed to the non-plastic m allele

r 1, r 2

Recombination rates associated with the two alleles at the recombination modifier locus, which determines the recombination rate between the plasticity modifier locus and the target locus

R

Recombination rate between the recombination modifier locus and the plasticity–target sequence

r′

Recombination rate between two target loci

r*

The ES recombination rate, a recombination rate that cannot be displaced by any other rate in a given selection regime
