Genetic exchange also happens between distantly related organisms by horizontal gene transfer, or HGT.

HGT is particularly important to prokarytotes and is the most common way by which they acquire new genes.

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

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.

This suppression of recombination allows alleles adapted to a specific environment to remain together, unshuffled by recombinationsomes cannot produce viable progeny.
