The for gene that codes for PKG (an important cell signaling molecule) influences not only locomotion during foraging, but also readiness to respond to sucrose, and tendencies to habituate to repeated presentations of sucrose. This illustrates the principle that
A) a gene's activity may be modified by using RNAi.
B) genes operate in interacting networks.
C) one gene is usually dedicated to a particular, primary trait.
D) one gene usually affects several traits.

One gene can influence multiple traits, a concept known as pleiotropy. The example of the gene coding for PKG affecting various behaviors related to foraging and response to sucrose illustrates this principle.
