Solved problem S2 illustrates the consequences of crossing over between the direct and inverted repeats within a single TE. The drawing here shows the locations of two copies of the same TE within a single chromosome. The chromosome is depicted according to its G banding pattern. The direct and inverted repeats are labeled 1, 2, 3, and 4, from left to right.

Draw the end result of recombination between the following sequences. Your drawing should include the banding pattern of the resulting chromosome.
A. DR-1 and DR-4
B. IR-1 and IR-4
