The following point highlight the five main types of structural variation in chromosomes. The types are: 1. Deletion or Deficiency 2. Duplications 3. Translocations 4. Inversions 5. B-Chromosomes. Type # 1. Deletion or Deficiency: A deficiency means deletion of a small portion of a chromosome resulting in loss of one or more genes. A deficiency originates from breakage occurring at [...]
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 [...]
