Polymorphism interactions between SP and SPR. The two most significant interactions between SP and SPR are shown. (A) An intronic indel in SP interacts with a synonymous SNP in SPR. The P1 score of the male alleles is dependent on the female allele. Males have similar P1 scores when females carry the SPR C allele. However, there is an approximately eightfold difference in P1 scores between the male SP alleles when the female carries the SPR T allele. (B) A synonymous SNP in SP interacts with a synonymous SNP in SPR. The rank order of male SP allele changes dependent on the female SPR allele. Significance was tested by a log-linear model.
