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 [...]
In this article we will discuss about the interchanges involving more than two pairs of chromosomes. When 3 or more pairs of non-homologous chromosomes are involved in translocation, it is called a complex translocation, complex interchange or multiple translocation. In a single cell, two or more independent heterozygous interchanges show two or more quadruples at MI. Such interchanges are obtained [...]
In this article we will discuss about the translocation in humans. Interchanges are the most common structural chromosome changes reported in human. Partial sterility in interchange heterozygotes is infrequent due to the production of balanced gametes and as a result, interchanges in human are identifiable only through the analysis of karyotype, usually coupled with chromosome banding patterns. Various kinds of [...]
