WebReciprocal translocation is a chromosomal anomaly due to genetic mutation. Its incidence is quite frequent in about 1 in 500 or 0.14% of newborns. Rearrangement of genes leads to the mutual exchange of broken-off chromosomal segments between non-homologous chromosomes.
WebBalancer chromosomes can also be used in genetic screens to find mutations. See Fig. 7.9. Translocation: A chromosomal rearrangement in which part of one chromosome becomes attached to a non-homologous chromosome (non-reciprocal), or in which parts of two non-homologous chromosomes trade places (reciprocal). open thanksgiving 2021Reciprocal translocations are usually an exchange of material between non-homologous chromosomes and occur in about 1 in 491 live births. Such translocations are usually harmless, as they do not result in a gain or loss of genetic material, though they may be detected in prenatal diagnosis.
