  2. Comparative genomics - Wikipedia

    en.wikipedia.org/wiki/Comparative_genomics

    Pairwise Comparison: The Pairwise comparison of genomic sequence data is widely utilized in comparative gene prediction. Many studies in comparative functional genomics lean on pairwise comparisons, wherein traits of each gene are compared with traits of other genes across species. his method yields many more comparisons than unique ...

  3. Model organism - Wikipedia

    en.wikipedia.org/wiki/Model_organism

    The primary reason for the use of model organisms in research is the evolutionary principle that all organisms share some degree of relatedness and genetic similarity due to common ancestry. The study of taxonomic human relatives, then, can provide a great deal of information about mechanism and disease within the human body that can be useful ...

  4. QST (genetics) - Wikipedia

    en.wikipedia.org/wiki/QST_(genetics)

    In quantitative genetics, Q ST is a statistic intended to measure the degree of genetic differentiation among populations with regard to a quantitative trait. It was developed by Ken Spitze in 1993. [1] Its name reflects that Q ST was intended to be analogous to the fixation index for a single genetic locus (F ST).

  5. Sequence homology - Wikipedia

    en.wikipedia.org/wiki/Sequence_homology

    Sequence comparison methods were first pioneered in the COGs database in 1997. [8] These methods have been extended and automated in twelve different databases the most advanced being AYbRAH Analyzing Yeasts by Reconstructing Ancestry of Homologs [9] as well as these following databases right now. Some tools predict orthologous de novo from the ...

  6. Genomics - Wikipedia

    en.wikipedia.org/wiki/Genomics

    Genomics is an interdisciplinary field of molecular biology focusing on the structure, function, evolution, mapping, and editing of genomes.A genome is an organism's complete set of DNA, including all of its genes as well as its hierarchical, three-dimensional structural configuration.

  7. Molecular genetics - Wikipedia

    en.wikipedia.org/wiki/Molecular_genetics

    Molecular genetics is a branch of biology that addresses how differences in the structures or expression of DNA molecules manifests as variation among organisms. Molecular genetics often applies an "investigative approach" to determine the structure and/or function of genes in an organism's genome using genetic screens.

  8. Genomic imprinting - Wikipedia

    en.wikipedia.org/wiki/Genomic_imprinting

    This increase will also force a higher degree in testing capabilities and assortment of tests to determine the presences of imprinting. When a locus is identified as imprinted, two different classes express different alleles. [65] Inherited imprinted genes of offspring are believed to be monoallelic expressions.

  9. Hardy–Weinberg principle - Wikipedia

    en.wikipedia.org/wiki/Hardy–Weinberg_principle

    There is 1 degree of freedom (degrees of freedom for test for Hardy–Weinberg proportions are # genotypes − # alleles). The 5% significance level for 1 degree of freedom is 3.84, and since the χ 2 value is less than this, the null hypothesis that the population is in Hardy–Weinberg frequencies is not rejected.
