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? A)result M B)result H C)result K D)result L E)None of the answer options is correct.

Result D shows that there is no significant difference between the mean phenotype of the two strains across all three environments. This indicates an absence of genotype-by-environment interaction, as both strains respond similarly to the varying levels of environmental stimulation. In contrast, the other results show varying degrees of interaction, where the difference between the strains depends on the specific environment.
