Consequences of mate choice: progeny sex ratio, inheritance of allele CR and sex-ratio selection acting on allele CR. On the left: simulations starting with XX/XY system with scenarios 10% CR (a) and 90% CR (b). On the right: simulations starting with ZW/ZZ system with scenarios 10% CR (c) and 90% CR (d). In each panel, the top three curves show the changes in adult sex ratio (ASR) and progeny sex ratio (PSR) of mothers preferring sex-reversed and normal males (CR and CN mothers, respectively); the four curves in the middle show the relative frequency of allele CR across and among sexes (CR in adults, CR in adult females, CR in adult males) and the relative frequency of CR among preference alleles inherited by offspring from their fathers (CR from father; note how it differs from the CR in adult males). Mothers passed on allele CR with a relative frequency corresponding to its presence among adult females (not shown). The bottom curve of each panel shows the strength of sex-ratio selection (s) relative to the effective population size (Ne), expressed as s–1/(2Ne) (this value is shown instead of s itself, because the effect of genetic drift can override s in small populations). Each curve indicates median values calculated from 100 runs (see Additional file 4: Fig. S4 for the relative frequencies of CR in all individual runs). Vertical dotted lines indicate the end of each sex-determination period and dashed lines indicate the start of ultimate population decline. Note that the top, middle, and bottom part of each panel has three different Y axes and with different scales to facilitate visibility. Year zero refers to the start of climate warming
