Here we consider reciprocal translocations, the most common type. Band numbers indicate breakpoints. December In both the examples we have looked at, the chromosomes have been rearranged so that no chromosome material has been lost or gained. It is important to distinguish between chromosomal translocations occurring in gametogenesis, due to errors in meiosisand translocations that occur in cellular division of somatic cellsdue to errors in mitosis. In any case, for our purposes, Drosophila can tolerate a loss or an excess of heterochromatin with little effect on viability or fertility.

  • In genetics, chromosome translocation is a phenomenon that results in unusual rearrangement of chromosomes. This includes balanced and unbalanced.

    Translocation Talking Glossary of Genetic Terms NHGRI

    The following information discusses what chromosome translocations are, how they are inherited and when they might cause problems. This information is. When two nonhomologous chromosomes mutate by exchanging parts, the resulting chromosomal rearrangements are translocations. Here we consider.
    Retrieved March 4, Cytologia 59 : Through the genome analysis of various species of Sophora Leguminosae and the integration of this data with morphological, palynological, and biochemical studies, these species were taxonomically relocated to the genus Sophora and Styphnolobium Palomino et al.

    In our laboratory we obtained the DNA content of various species by scanning microphotometry and, recently, by flow cytometry Dolezel, From this information the basic number of genetic linkage groups x can be determined, as well as how often they are repeated, providing a rapid indicator of the genetic similarity between populations or species.

    A Robertsonian translocation occurs when one chromosome becomes attached to another. This is called a balanced translocation. Translocations, inversions, and deletions produce partial sterility by generating unbalanced meiotic products that may themselves die or that may cause zygotes to die. Karyotype analysis in three new species of Echeandia Liliaceae and cytotypes of E.

    Somatic translocations, on the other hand, result in abnormalities featured only in the affected cell line, as in chronic myelogenous leukemia with the Philadelphia chromosome translocation. From this information the basic number of genetic linkage groups x can be determined, as well as how often they are repeated, providing a rapid indicator of the genetic similarity between populations or species.

The content in the tetraploid taxa was double in relation with those obtained in the diploid taxa, which suggests that the Leucaena tetraploid taxa are of recent origin, and have not yet been through a genome reduction process Grant, This is called prenatal diagnosis and is something you may wish to discuss with the genetic specialist more information about these tests are available in the CVS and amniocentesis leaflets.
