In the following graph, which line (1 to 3) better represents the changes in the level of EphA receptors on retinal axons along the anterior-posterior axis of the mouse retina? Which line better represents the changes in the abundance of EphrinA along the anterior-posterior axis of the mouse optical tectum? Write down your answer as a two-digit number, e.g. 22.

Neurons in the posterior retina express EphA. Their axons are repelled by high levels of EphrinA protein in the posterior tectum and thus project preferentially to the anterior tectum.
