Which of the following is true about gene-environment interactions and trait expression?
A) If two individuals have the same behaviors of a trait, they must share the same gene for that trait.
B) If two individuals share the same gene for a trait, they must have the same behaviors of that trait.
C) If two individuals have the same behaviors of a trait, they must share the same gene for that trait, but two individuals can share the same gene for the trait and have differing behaviors of that trait.
D) Two individuals can have the same gene for a trait and have differing behaviors of that trait, and two individuals can have the same behaviors of but have differing genes for the trait.

Option D is correct because it acknowledges the complexity of gene-environment interactions in determining trait expression. It recognizes that the same gene can result in different behaviors under different environmental conditions and that similar behaviors can arise from different genetic backgrounds due to the influence of the environment.
