In this article we will discuss about the translocation of organic substances in phloem. An organised transport system is essential for the efficient functioning of different organs in a multicellular plant. Nutrients were absorbed from the soil through the roots and are utilized in rest of the organs of the plant. Similarly, metabolites are synthesized in the leaves and are [...]
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 [...]
