    en.wikipedia.org/wiki/Sex_verification_in_sports

    Compulsory sex verification tests were commonplace and not many female athletes questioned the practice until the late 1980s. [14] Chromosome testing was criticized by scientists, such as de la Chapelle, Ferguson-Smith, Ferris, Ljungqvist, and Simpson.

  3. Genetic testing - Wikipedia

    en.wikipedia.org/wiki/Genetic_testing

    Genetic testing is often done as part of a genetic consultation and as of mid-2008 there were more than 1,200 clinically applicable genetic tests available. [23] Once a person decides to proceed with genetic testing, a medical geneticist, genetic counselor, primary care doctor, or specialist can order the test after obtaining informed consent .

    Alec Jeffreys. After finishing his doctorate, he moved to the University of Amsterdam, where he worked on mammalian genes as a research fellow, [15] and then to the University of Leicester in 1977, where in 1984 he discovered a method of showing variations between individuals' DNA, inventing and developing genetic fingerprinting.

    1911: Alfred Sturtevant, one of Morgan's collaborators, invented the procedure of linkage mapping which is based on the frequency of crossing-over. [14] 1913: Alfred Sturtevant makes the first genetic map, [15] showing that chromosomes contain linearly arranged genes.

    Thomas Hunt Morgan discovered sex linked inheritance of the white eyed mutation in the fruit fly Drosophila in 1910, implying the gene was on the sex chromosome. In 1910, Thomas Hunt Morgan showed that genes reside on specific chromosomes. He later showed that genes occupy specific locations on the chromosome.

  7. 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 ...

  8. Forensic DNA analysis - Wikipedia

    en.wikipedia.org/wiki/Forensic_DNA_analysis

    Developed in 1991, [10] DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. [11] This technique allowed for the use of far fewer cells than RFLP analysis making it more useful for crime scenes that did not have the large amounts of DNA material that was previously required. [ 12 ]

    Kary Banks Mullis (December 28, 1944 – August 7, 2019) was an American biochemist.In recognition of his role in the invention of the polymerase chain reaction (PCR) technique, he shared the 1993 Nobel Prize in Chemistry with Michael Smith [2] and was awarded the Japan Prize in the same year.
