Achromosome has an inversion. which describes a pericentric inversion? deletion of genes within the same chromosome arm switching of genes within the same chromosome arm switching of genes around the centromere deletion of genes around the centromere

Inversion is a type of chromosome rearrangement in which chromosome segment is inverted end to end. There is no deletion or addition of segments, segments just change invert in the chromosome. There are two types of inversions - paracentric and pericentric.

Paracentric inversion does not include centromere. Genes are switched within one of the arms of the chromosome.

Pericentric inversion includes centromere, so genes are switched around it.

switching of genes around the centromere

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.
