WebA translocation, where a piece of one chromosome gets attached to another chromosome. A reciprocal translocation involves two chromosomes swapping segments; a non-reciprocal translocation means that a chunk of one chromosome moves to another. 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… pratt ks city map

Robertsonian Translocation: All You Need to Know

WebJun 18, 2024 · Balanced translocations can be categorized into reciprocal translocations, characterized by the exchange of genetic material between the two non-homologous chromosomes, and Robertsonian translocations, which occur as a result of a fusion of two acrocentric chromosomes (chromosomes 13, 14, 15, 21 or 22). WebIn a Robertsonian translocation, an entire chromosome attaches to another at the centromere: This newly formed chromosome is called the translocation chromosome.
