Now onto our "two" chord (ii). 

The chord tones discussed here will directly relate to the matching mode, dorian.

In this case A dorian because the ii chord of Gmaj is Amin7.

A - B - C - D - E - F# - G (A -  B  -  C  -  D  -   E  -  F#  - A)

1 - 2 - b3 - 4 - 5 - 6 -b7 (- 8 - 9 - b10 - 11 - 12 - 13 - b14)

Within the two chord some people would exclude the 13 as an extension since it creates a tritone between the b3 and 13, BUT it sounds great and it is a characteristic note of dorian that sets it appart.

So there are no avoid notes!

Extensions - 9, 11, & 13

Avoid notes - none
