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… WebHumans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 18, one copy inherited from each parent, form one of the pairs. …
WebThe extra chromosome 18 or 13 can come from either the mother's egg cell or the father's sperm cell. In some instances, the extra chromosome 18 or 13 is attached to another chromosome in the egg or sperm. This is called translocation and is the only form of trisomy 18 or 13 that can be inherited.
