Chromosome Multiplication

Translocation

Translocation is a type of chromosomal abnormality in which a chromosome breaks and a portion of it reattaches to a different chromosome. Chromosomal translocations can be detected by analyzing karyotypes of the affected cells.

Deletion

Deletion is a type of mutation involving the loss of genetic material. It can be small, involving a single missing DNA base pair, or large, involving a piece of a chromosome.

Ring Chromosome

A ring chromosome is denoted by the symbol r in human genetics and R in Drosophila genetics. Ring chromosomes may form in cells following genetic damage by mutagens like radiation, but they may also arise spontaneously during development.

Lsochromosmes

An isochromosome is an unbalanced structural abnormality in which the arms of the chromosome are mirror images of each other. The chromosome consists of two copies of either the long arm or the short arm because isochromosome formation is equivalent to a simultaneous duplication and deletion of genetic material.

Paracentric Inversion

A paracentric inversion occurs when a portion of one chromosome , or a packet of genetic information, is flipped so that the order of genetic information changes. Each chromosome has a portion near the middle called a centromere . Paracentric inversions do not include a chromosome's centromere.
