Pairing during meiosis requires the formation of an inversion loop. Pericentric Inversion in Chromosome 10 in a Girl, Inherited from a Crossing over is the swapping of genetic material that occurs in the germ line. Why does Paracentric inversion lead to dicentric bridges? An inversion that occurs in the long (q) arm or short (p) arm and does not involve the centromere is called a paracentric inversion. The cell(s) have the same number of copies of all the chromosome. What is Pericentric inversion of chromosome? Pairing during meiosis requires the formation of an inversion loop. [] If both breakpoints are on the same side of the centromere, the inversion is paracentric; if they are on both sides of the centromere, then it is pericentric inversion. The differences between these two types of inversions are -. Pericentric inversions include the centromere, while paracentric inversions occur outside of the centromere; a pericentric inversion can change the length of the chromosome arms above and below the centromere. This happens between the two innermost sister chromatids. Moreover, both types of inversions do not cause a loss of genetic information.

Privacy Policy3. On the other hand in Drosophila, reduced gametic fertility may be the reason for the low frequency of observed pericentric inversions surviving in the natural populations. Overview and Key Difference Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.
