In this article we will learn about:- 1. Origin of Inversions 2. Types of Inversion 3. Effects 4. Uses. Origin of Inversions: Inversion was first discovered by Sturtevant in 1921 in Drosophila. Later it was detected in a wide variety of plant and animal species. Inversions occur spontaneously, and can be induced artificially. In many […]

Paracentric Inversion in Chromosome (With Diagram)
Article Shared by
In this article we will discuss about the paracentric inversion in chromosome. Chromosome Pairing and Crossing Over: In paracentric inversions chromosome pairing occurs by loop formation in the inverted region; the centromere remains outside the loop. Crossing over in the loop causes the formation of dicentric chromatids which produce bridges at anaphase. Chromatid bridges may […]
Inversions in Natural Populations
Article Shared by
In this article we will discuss about the inversions in natural populations which is caused when the genes in a section of a chromosome is reversed. Inversions occur spontaneously in a large number of plant and animal species. But the most extensive work has been done in Drosophila in which they have been detected in […]
