Definition of paralogy in English:



  • 1Genetics
    The state of being paralogous.

    • ‘Our goal therefore was to determine to which group individual sequences belong in order to clarify orthology and paralogy and to provide a framework for gene comparisons.’
    • ‘This shows that the acquisition of catalase activity, whether by paralogy or by lateral acquisition of genes, will usually lead to a better performance of aerobic organisms.’
    • ‘Second, in the study of Baldauf et al., hidden paralogy can be problematic, since many paralogs exist within animals for three of the four genes used (actin, and - and ß-tubulins) and finding the correct orthologs is difficult.’
    • ‘We analyzed the concatenated alignment of previously available amino acid sequences, although the possibility of paralogy could not be completely excluded.’
    • ‘Generally, the analysis of substitution rates in multicopy genes requires careful handling of orthology and paralogy.’
  • 2Paralogical reasoning.

    • ‘Lyotard sees reason not as a universal and immutable human faculty or principle but as a specific and variable human production; "paralogy" for him means the movement against an established way of reasoning.’
