  2. Tajima's D - Wikipedia

    en.wikipedia.org/wiki/Tajima's_D

    Tajima's D is a population genetic test statistic created by and named after the Japanese researcher Fumio Tajima. [1] Tajima's D is computed as the difference between two measures of genetic diversity: the mean number of pairwise differences and the number of segregating sites, each scaled so that they are expected to be the same in a neutrally evolving population of constant size.

  3. Genetic testing - Wikipedia

    en.wikipedia.org/wiki/Genetic_testing

    DTC genetic testing involves many of the same risks associated with any genetic test. One of the more obvious and dangerous of these is the possibility of misreading of test results. Without professional guidance, consumers can potentially misinterpret genetic information, causing them to be deluded about their personal health.

  4. Test cross - Wikipedia

    en.wikipedia.org/wiki/Test_cross

    In a test cross, the individual in question is bred with another individual that is homozygous for the recessive trait and the offspring of the test cross are examined. [2] Since the homozygous recessive individual can only pass on recessive alleles, the allele the individual in question passes on determines the phenotype of the offspring. [3]

  5. Genealogical DNA test - Wikipedia

    en.wikipedia.org/wiki/Genealogical_DNA_test

    A genealogical DNA test is a DNA-based genetic test used in genetic genealogy that looks at specific locations of a person's genome in order to find or verify ancestral genealogical relationships, or (with lower reliability) to estimate the ethnic mixture of an individual. Since different testing companies use different ethnic reference groups ...

  6. Gene by Gene - Wikipedia

    en.wikipedia.org/wiki/Gene_by_Gene

    With the opening of the GRC, Greenspan and Blankfeld formed additional business units between 2008 and 2012 under the Genealogy by Genetics company to sell non-genealogical genetic tests. [18] [19] They launched DNA Traits in 2008. In an interview in 2008, Greenspan said "Mendelian disorders are genealogy—we either have had a disaster in our ...

  7. DNA bank - Wikipedia

    en.wikipedia.org/wiki/DNA_bank

    DNA banks allow for conservation of genetic material and comparative analysis of an individual's genetic information. Analyzing an individual's DNA can allow scientists to predict genetic disorders , as used in preventive genetics or gene therapy , and prove that person's identity, as used in the criminal justice system .

  8. Biobank - Wikipedia

    en.wikipedia.org/wiki/Biobank

    Genome-wide association studies using data from tens or hundreds of thousands of individuals can identify these genetic associations as potential disease biomarkers. Many researchers struggled to acquire sufficient samples prior to the advent of biobanks. Biobanks have provoked questions on privacy, research ethics, and medical ethics.

  9. Elective genetic and genomic testing - Wikipedia

    en.wikipedia.org/wiki/Elective_genetic_and...

    Elective genetic and genomic testing are DNA tests performed for an individual who does not have an indication for testing. An elective genetic test analyzes selected sites in the human genome while an elective genomic test analyzes the entire human genome. Some elective genetic and genomic tests require a physician to order the test to ensure ...
