An inversion is a chromosome rearrangement in which a segment of a chromosome becomes inverted within its original position. An inversion occurs when a chromosome undergoes a two breaks within the chromosomal arm, and the segment between the two breaks inserts itself in the opposite direction in the same chromosome arm.
28 Σεπ 2010 · An inversion occurs when a chromosome breaks at two points and the segment bounded by the breakpoints is reinserted in the reversed orientation. Several molecular mechanisms can mediate this event . Box 1 gives an overview of some basic properties of inversions and the ways that they are detected.
Inversions are structural mutations that reverse the sequence of a chromosome segment and reduce the effective rate of recombination in the heterozygous state. They play a major role in adaptation, as well as in other evolutionary processes such as speciation.

4 ημέρες πριν · An inversion in a chromosome occurs when a segment breaks off and reattaches within the same chromosome, but in reverse orientation. DNA may or may not be lost in the process.
20 Μαΐ 2022 · Inversions happen when a piece of DNA in a chromosome gets reversed – meaning it is in the right place in the right chromosome, but the wrong way round. They can occur anywhere in the genome, but they may be more common in some regions than others.
In chromosomal inversion, a DNA segment of a chromosome is reversed end to end, which takes place when a single chromosome undergoes breakage and rearrangement within itself (Fig. 1 B). Two types of inversion exist, i.e., paracentric and pericentric.
