  2. Mutation (evolutionary algorithm) - Wikipedia

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

    One possible form of changing the value of a gene while taking its value range [,] into account is the mutation relative parameter change of the evolutionary algorithm GLEAM (General Learning Evolutionary Algorithm and Method), [17] in which, as with the mutation presented earlier, small changes are more likely than large ones.

  4. Mutation - Wikipedia

    en.wikipedia.org/wiki/Mutation

    A germline mutation in the reproductive cells of an individual gives rise to a constitutional mutation in the offspring, that is, a mutation that is present in every cell. A constitutional mutation can also occur very soon after fertilization , or continue from a previous constitutional mutation in a parent. [ 90 ]

  5. 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 ...

  6. Loss of heterozygosity - Wikipedia

    en.wikipedia.org/wiki/Loss_of_heterozygosity

    The remaining copy of the tumor suppressor gene can be inactivated by a point mutation or via other mechanisms, resulting in a loss of heterozygosity event, and leaving no tumor suppressor gene to protect the body. Loss of heterozygosity does not imply a homozygous state (which would require the presence of two identical alleles in the cell).

  7. Evolution by gene duplication - Wikipedia

    en.wikipedia.org/wiki/Evolution_by_gene_duplication

    If a gene duplication is preserved, the most likely fate is that random mutations in one duplicate gene copy will eventually cause the gene to become non-functional . [3] Such non-functional remnants of genes, with detectable sequence homology , can sometimes still be found in genomes and are called pseudogenes .

  8. Genomic imprinting - Wikipedia

    en.wikipedia.org/wiki/Genomic_imprinting

    Each autosomal gene is therefore represented by two copies, or alleles, with one copy inherited from each parent at fertilization. The expressed allele is dependent upon its parental origin. For example, the gene encoding insulin-like growth factor 2 (IGF2/Igf2) is only expressed from the allele inherited from the male. Although imprinting ...

  9. Copy number variation - Wikipedia

    en.wikipedia.org/wiki/Copy_number_variation

    Copy number variation (CNV) is a phenomenon in which sections of the genome are repeated and the number of repeats in the genome varies between individuals. [1] Copy number variation is a type of structural variation: specifically, it is a type of duplication or deletion event that affects a considerable number of base pairs. [2]
