Please explain how that answer is derived?

Saroja said: (Jul 16, 2013)  
Could you please explain me how it would be occur in paracentric inversion?

A.N. said: (Nov 17, 2017)  
Paracentric inversions exclude the centromere with an occurrence of break in only one arm of chromosome.

Whereas,
Pericentric chromosome include centromere and break in both arms of chromosome.

Priya Sharma said: (Mar 30, 2018)  
Paracentric inversion:Two breaks on one side of centromere; arm ratio is unchanged.

Pericentric inversion:one break in each arm:often arm ratio is changed. Recombination have duplication and deficiency of chromosomes segment.
