The following points highlight the top fifteen uses of translocation in genetics. The uses are: 1. Study of chromosome behaviour during meiosis 2. Assignment of centromere position 3. Interchanges as genetic markers 4. Determination of unknown locus of a gene and chromosome mapping 5. Association of linkage groups or genes to specific chromosomes and a Few Others. Uses of Translocation [...]
The following points highlight the five specific types of translocation in genetics. The types are: 1. Pseudo-Iso-Chromosomes 2. Interdependent Rings 3. Cyclic or Progressive Translocation 4. Duplication-Deficiency Interchange Heterozygotes 5. Interchanges between Normal and Supernumerary Chromosomes. Translocation: Type # 1. Pseudo-Iso-Chromosomes: This term was coined by Caldecott and Smith in 1952: it may be defined as a chromosome the two [...]
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 organisms, inversions are found in [...]
