  2. 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 ...

  3. Genetic testing - Wikipedia

    en.wikipedia.org/wiki/Genetic_testing

    Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression , or through biochemical analysis to measure specific protein output.

  4. Forensic DNA analysis - Wikipedia

    en.wikipedia.org/wiki/Forensic_DNA_analysis

    A DQ alpha testing strip showing a positive result. The filled in dots represent the allele values for that sample. Developed in 1991, [10] DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. [11]

  5. Personal genomics - Wikipedia

    en.wikipedia.org/wiki/Personal_genomics

    Personal genomics or consumer genetics is the branch of genomics concerned with the sequencing, analysis and interpretation of the genome of an individual. The genotyping stage employs different techniques, including single-nucleotide polymorphism (SNP) analysis chips (typically 0.02% of the genome), or partial or full genome sequencing.

  6. Sequence homology - Wikipedia

    en.wikipedia.org/wiki/Sequence_homology

    Sequence homology is the biological homology between DNA, RNA, or protein sequences, defined in terms of shared ancestry in the evolutionary history of life. Two segments of DNA can have shared ancestry because of three phenomena: either a speciation event (orthologs), or a duplication event (paralogs), or else a horizontal (or lateral) gene ...

  7. Genotyping - Wikipedia

    en.wikipedia.org/wiki/Genotyping

    Genotyping is the process of determining differences in the genetic make-up of an individual by examining the individual's DNA sequence using biological assays and comparing it to another individual's sequence or a reference sequence.
