Inversion

Inversion is a form of chromosome mutation – structural abnormality.


 * For inversion are typical two breaks in the different part of the chromosome. The newly created segments then replace each other.
 * Inversion was discovered in 1921.
 * Although we still don´t know why inversion exists, we know that it is the most important mechanism of reorganizing of the genome.
 * We recognize 2 types of inversion:
 * 1) pericentric – causing deletions, insertions or abnormal centromeres.
 * 2) paracentric – more common type, it is less harmfull for its carrier.


 * Inversion suppress the recombination process.
