Pericentric Inversion: Meaning and Occurrence

In this article we will discuss about:- 1. Meaning of Pericentric Inversion 2. Chromosome Morphology 3. Occurrence of Pericentric Inversion. Meaning of Pericentric Inversion: When the inverted segment is large, a loop is formed during synapsis and centromere is included in the loop. Crossing over in the loop causes the formation of deficiency-duplication chromatids. Chromosome pairing and crossing over positions [...]

Genetical and Cytological Methods of Locating Inversion Break Points

In this article we will discuss about the genetical and cytological methods of locating inversion break points. Cytological Location: Cytological analysis is an important method of the physical location of the break points of inversion. (a) In plants like maize, and other organisms where pachytene analysis is easy, the breakpoints can be located by measuring the position of the inversion [...]
