Under this form of testing, the blood types of the child and parents are compared, and it can be determined whether there is any possibility of a parental link. For example, two O blood type parents can produce a child only with an O blood type, and two parents with a B blood type can produce a child with either a B or an O blood type.
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.
Example calculation of a paternity index. In paternity testing, Paternity Index (PI) is a calculated value generated for a single genetic marker or locus (chromosomal location or site of DNA sequence of interest) and is associated with the statistical strength or weight of that locus in favor of or against parentage given the phenotypes of the tested participants and the inheritance scenario.
This type of genetic testing can be used for cancer patients undergoing chemotherapy. [21] A sample of the cancer tissue can be sent in for genetic analysis by a specialized lab. After analysis, information retrieved can identify mutations in the tumor which can be used to determine the best treatment option. [22]
STR analysis can also be restricted to just the Y chromosome. Y-STR analysis can be used in cases that involve paternity or in familial searching as the Y chromosome is identical down the paternal line (except in cases where a mutation occurred). Certain multiplexing kits combine both autosomal and Y-STR loci into one kit further reducing the ...
