Not, I think, in the scenario being proposed. This unmutated gene is an allele at the same locus as the mutated one. When the mutant becomes fixed in the population, the unmutated gene is gone. Now, if the mutation is preceded by gene duplication, it would be the mutated gene, the broken one, that would be in the junk DNA. Junk is not long-term memory; it’s just junk.
