Reciprocal Translocation Against GA-Deceptiveness

2005 IEEE Congress on Evolutionary Computation, 2005
Reciprocal translocation is a nature-inspired crossover operator that is proved to be a useful alternative for the conventional multipoint and uniform crossover operators. This paper compares the performance of reciprocal translocation against the well-known conventional crossover operators for the solution of provably difficult GA-deceptive functions.

Lack of reciprocal translocations in carcinomas

Cancer Genetics and Cytogenetics, 1986
Among the varied structural chromosomal aberrations present in the common forms of carcinoma, reciprocal translocations generally appear to be lacking. Although the breakpoints may be variable, the chromosomal changes nevertheless commonly result in the loss or gain of particular chromosomal segments. The possible implications of these observations are

Partners with reciprocal translocations: genetic counseling for the ‘double translocation’

Clinical Genetics, 1998
SV at age 2 years presented with multiple congenital anomalies including an absent left kidney, anal stenosis, vertebral abnormalities, partial sacral agenesis, microcephaly, dysmorphic facial features, growth deficiency, and developmental delay. She was found to have a complex chromosomal rearrangement derived from balanced translocations in each ...

Autosomal Reciprocal Translocations

2018
Abstract This chapter reviews in detail the question of carriers of autosomal reciprocal translocations and the genetic risks implied for potential offspring of theirs. Examples are put forward of the various possibilities due to malsegregation in gametes of theirs: adjacent-1, adjacent-2, 3:1, and the (very rare) 4:0 malsegregation ...

Topology of constitutional reciprocal translocations in metaphase

Annales de Génétique, 2004
We studied in 39 carriers of 26 reciprocal translocations (including five de novo and seven of indeterminate occurrence) the metaphase localization of the derivative chromosomes, their normal non-homologous counterparts (here called A and B), and two control pairs (C and D). In eight familial translocations, we analysed two to five carriers.

Segregation analysis in reciprocal translocation carriers

American Journal of Medical Genetics, 1984
AbstractSegregation analysis of the offspring of balanced translocation carriers was performed on 327 pedigrees collated from published sources and personal communications. Correction was made for bias of ascertainment. Translocations studied involved chromosome arms 1p, 4q, 6p, 6q, 7p, 8p, 10p, 10q, 11q, 14q, 16q, and 17p.

Autosomal Reciprocal Translocations

2011
Abstract RECIPROCAL TRANSLOCATIONS ARE COMMON, and every counselor can expect to see translocation families. The usual form is the simple, or two-way, reciprocal translocation: only two chromosomes, usually autosomes, are involved, with one breakpoint in each. It is this category we consider in this chapter.

Double reciprocal translocation heterozygosity in a bull

Veterinary Record, 1982
A double reciprocal translocation has been found in a morphologically normal but infertile bull (Bos taurus), using trypsin-Giemsa banding. The karyotype of the bull can be written as: 60,XY,t(2q-;20q+),t(8q-;27q+). Cytophotometric studies supported the findings in the karyograms and identified the breakpoints in the chromosomes involved.

Translocation (1;19)(q21;q13.3) is a recurrent reciprocal translocation in meningioma

Cancer Genetics and Cytogenetics, 2002
Benign meningiomas are characterized by a normal karyotype or loss of all or part of chromosome 22. Histologically higher grade tumors are typically characterized by a pattern of increasing chromosome loss and instability. This characteristic pattern of unbalanced chromosome aberrations is punctuated in the literature by several intriguing reports of a

A de novo translocation in a family with a balanced reciprocal chromosomal translocation

Clinical Genetics, 1986
A carrier of a reciprocal translocation between chromosomes 10 and 18 had a child with a reciprocal translocation involving different segments of the same chromosomes. The categories of possible meiotic errors in carriers of balanced rearrangements must, therefore, be expanded to include new reciprocal translocations.
