The plots shown here depict several possible outcomes of an experiment comparing the mean phenotype of a behavioral trait in two strains of mice in three environments. Strain 1 is represented by filled circles and Strain 2 is represented by open circles. Environment 1 (E1) is deficient in stimulation for the behavior, environment 2 (E2) has an average level of stimulation, and environment 3 (E3) is enriched in stimulation. Which of the possible results indicates the absence of genotype-by-environment interaction?
