IS2-61 and IS2-611 arise by illegitimate recombination from IS2-6.
A more stable derivative of IS2-6 has been isolated, which had lost 54 bp of the 108 bp long insert characteristic of IS2-6. This new allele of IS2, IS2-61, segregates the remaining 54 bp to yield allele IS2-611. DNA sequence analysis shows that the segregation products of IS2-6 arise by recA-independent, illegitimate recombination at 9 bp long direct sequence repetitions.
