Answer:
we'll use () to indicate the different boxes
( ) (r) (r)
(R) (Rr) (Rr)
(R) (Rr) (Rr)
You will have a 2 by 2 cell for your answer. One set of your test (rr) will go across the top as is shown and the other will be vertical (RR) as shown. Go down the line and put the letter you see at the top in each box and then do the same going across.
( ) (r) (r)
( ) (r) ( )
( ) (r) ( )
( ) (r) (r)
(R) (Rr) (R)
(R) (r) ( )
