Derivative chromosome vs translocation
WebFeb 28, 2024 · The regions exchanged comprise about 20% (chromosome 4) and 30% (chromosome 16) of the two translocation chromosomes. Thus, they can be easily recognised by their changed size and altered centromere index. For exact localisation of the breakpoints, a banding resolution of at least 700 bands per genome is recommended. Cave In genetics, chromosome translocation is a phenomenon that results in unusual rearrangement of chromosomes. This includes balanced and unbalanced translocation, with two main types: reciprocal-, and Robertsonian translocation. Reciprocal translocation is a chromosome abnormality caused by exchange of parts between non-homologous chromosomes. Two detached fragments of tw…
