Question

Plz I need the different between paracentric and pericentric chromosome inversion. It urgent plz

Answer 1

Paracentric  

Paracentric inversions does not occur in the centromere. Crossing over only occurs in the out The loop occur in one arm of the chromosome. The result is a large loop in where recombination occurs in only part of the loop. Dicentric bridges (two loops) can form in the center of the chromosome where recombination does not occur. An acentric loop also occurs in the centromere region. The result is recombination in one loop.

Pericentric  

Pericentric inversion does occur in the centromere (in some cases). The most important part is that the chromosome can be elongated or shorted after the inversions have taken place. Deletions and duplications can occur during crossing over during the inversion. The result is recombination in two loops.
