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

#Unit 8. Inheritance Biology

Recombinant chromosomes have too many copies of some genes and no copies of others, so gametes that receive the recombinant chromosomes cannot produce viable progeny.

With the use of standard cytological methods, pericentric inversions are much easier to detect than paracentric inversions.
