  2. Chromosomal inversion - Wikipedia

    en.wikipedia.org/wiki/Chromosomal_inversion

    An inversion is a chromosome rearrangement in which a segment of a chromosome becomes inverted within its original position. An inversion occurs when a chromosome undergoes a two breaks within the chromosomal arm, and the segment between the two breaks inserts itself in the opposite direction in the same chromosome arm.

  3. Structural variation - Wikipedia

    en.wikipedia.org/wiki/Structural_variation

    Genomic structural variation is the variation in structure of an organism's chromosome, such as deletions, duplications, copy-number variants, insertions, inversions and translocations. Originally, a structure variation affects a sequence length about 1kb to 3Mb, which is larger than SNPs and smaller than chromosome abnormality (though the ...

  5. Chromosomal rearrangement - Wikipedia

    en.wikipedia.org/wiki/Chromosomal_rearrangement

    In genetics, a chromosomal rearrangement is a mutation that is a type of chromosome abnormality involving a change in the structure of the native chromosome. [1] Such changes may involve several different classes of events, like deletions, duplications, inversions, and translocations.

  6. Mutation (evolutionary algorithm) - Wikipedia

    en.wikipedia.org/wiki/Mutation_(evolutionary...

    This condition causes the mutation to always produce a genotypically altered chromosome. The start index can also be after the end index. Then the partial list simply starts again from the beginning (periodic boundary condition). This is necessary so that the permutation probability in the genome is the same everywhere and is not greater in the ...

  7. Karyotype - Wikipedia

    en.wikipedia.org/wiki/Karyotype

    Chromosome rearrangements, especially inversions, make it possible to see which species are closely related. The results are clear. The inversions, when plotted in tree form (and independent of all other information), show a clear "flow" of species from older to newer islands.

  8. Dicentric chromosome - Wikipedia

    en.wikipedia.org/wiki/Dicentric_chromosome

    Inversions that exclude the centromere are known as paracentric inversions, which result in unbalanced gametes after meiosis. [2] During prophase of meiosis I, homologous chromosomes form an inversion loop and crossover occurs. If a paracentric inversion has occurred, one of the products will be acentric, while the other product will be dicentric.
