How are you?

Let A,B,C,D,E,F,G,H be letters in your "genetic alphabet"
Let's say you have 2 strands of DNA:
1: ( (AFDD)BGHC(CE(ABABC)C)FG(GGD)HECD)
2: ((AB)EF(CGE)HCD(CHB)EA(HEC)HBA(ABB)BD)
What way can you think to mix the two?
Scrambling individual letters and sets of "(letters)" and then putting them into a new random order. That's one way.
But what's another way?
Each (grouping) can also have a "type"
Types can interact a specific way with another type.
So for example. in strand 2 (AB) and (ABB) can be of the same group type, typeA for instance. and when strand2 is spliced into strand1, all typeA's are cloned and shuffled into all typeB-groups.
Need more ways.
All of typeA could replace typeB
All of typeA's could be appended or prepended to typeB
All of typeA's should be flipped.
All of typeA's should shuffled.
Convert typeA's to typeB's
Still need more ideas. Just to make sure I get all of the mutation possibilities accounted for.
