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 [...]
In this article we will discuss about:- 1. Types of Duplications 2. Origin of Duplications 3. Chromosome Pairing 4. Phenotypic Effects of Duplications 5. Duplications in Human 6. Uses of Duplications. Types of Duplications: Broadly, duplications are divided into two types which are further subdivided into different subtypes. 1. Inter-Chromosomal duplication: The duplicated segment of a chromosome is present in [...]
In this article we will discuss about:- 1. Origin of Translocation 2. Types of Translocation 3. Effects. Origin of Translocation: Translocations can originate in the following different ways: (i) Translocations may originate spontaneously. (ii) They may be induced by mutagens, viz., ionizing radiations and many chemical mutagens, since they induce chromosome breakage. (iii) Translocations may be induced by growing plants [...]
