  2. Species translocation - Wikipedia

    en.wikipedia.org/wiki/Species_translocation

    Translocation is the human action of moving an organism from one area and releasing it in another. In terms of wildlife conservation , its objective is to improve the conservation status of the translocated organism or to restore the function and processes of the ecosystem the organism is entering.

  3. Chromosomal translocation - Wikipedia

    en.wikipedia.org/wiki/Chromosomal_translocation

    Chromosomal reciprocal translocation of the 4th and 20th chromosome. 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.

  4. 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. Gene flow - Wikipedia

    en.wikipedia.org/wiki/Gene_flow

    Species can live in the same environment, yet show very limited gene flow due to reproductive barriers, fragmentation, specialist pollinators, or limited hybridization or hybridization yielding unfit hybrids. A cryptic species is a species that humans cannot tell is different without the use of genetics.

  6. Gene conversion - Wikipedia

    en.wikipedia.org/wiki/Gene_conversion

    Gene conversion is the process by which one DNA sequence replaces a homologous sequence such that the sequences become identical after the conversion. [1] Gene conversion can be either allelic, meaning that one allele of the same gene replaces another allele, or ectopic, meaning that one paralogous DNA sequence converts another.

  7. Mobile genetic elements - Wikipedia

    en.wikipedia.org/wiki/Mobile_genetic_elements

    DNA transposons, LTR retrotransposons, SINEs, and LINEs make up a majority of the human genome. Mobile genetic elements (MGEs), sometimes called selfish genetic elements, [1] are a type of genetic material that can move around within a genome, or that can be transferred from one species or replicon to another. MGEs are found in all organisms.

  8. Translocation - Wikipedia

    en.wikipedia.org/wiki/Translocation

    Translocation may refer to: Chromosomal translocation, a chromosome abnormality caused by rearrangement of parts Robertsonian translocation, a chromosomal rearrangement in pairs 13, 14, 15, 21, and 22; Nonreciprocal translocation, transfer of genes from one chromosome to another; PEP group translocation, a method used by bacteria for sugar uptake

  9. Polytene chromosome - Wikipedia

    en.wikipedia.org/wiki/Polytene_chromosome

    Polytene chromosomes are also used to identify the species of chironomid larvae that are notoriously difficult to identify. Each morphologically distinct group of larvae consists of a number of morphologically identical (sibling) species that can only be identified by rearing adult males or by cytogenetic analysis of the polytene chromosomes of ...
