Is there a mutation that adds new genetic information?
gpt
As a basic example, you can have duplications. Instead of having one copy of gene A in the haploid genome, a duplication gives you two. Now, the two copies are free to accumulate different mutations. Say, A stays relatively conserved, still performing its original function, freeing up the second copy to change more freely, becoming A* with a different function. And there's your new information and functionality.
