Clustered Regularly Interspaced Short Palindromic Repeats CRISPR consist of repeated sequences (each 30 bp long and highly conserved within a given cluster) interleaved with spacer sequences of similar length but highly divergent sequence.

Recombination is also reduced within a pericentric inversion. No dicentric bridges or acentric fragments are produced.
