Disease testing: A complement to specific gene testing for monogenic disorders, which can be very useful for genetic diseases with sex linkage, such as, for example, X-linked diseases. In such cases, it may be much easier to exclude the possibility of disease in the child by prenatal sex discernment than to test for any specific sign of the ...
Sex verification in sports (also known as gender verification, or as gender determination or a sex test) occurs because eligibility of athletes to compete is restricted whenever sporting events are limited to a single sex, which is generally the case, as well as when events are limited to mixed-sex teams of defined composition (e.g., most pairs ...
[1] [2] Such variations may involve genital ambiguity, and combinations of chromosomal genotype and sexual phenotype other than XY-male and XX-female. [3] [4] Preimplantation genetic diagnosis allows the elimination of embryos and fetuses with intersex traits and thus has an impact on discrimination against intersex people.
DNA testing is currently the most advanced and accurate technology to determine parentage. In a DNA paternity test, the result (called the 'probability of parentage) [ 3 ] [ failed verification ] is 0% when the alleged parent is not biologically related to the child, and the probability of parentage is typically 99.99% when the alleged parent ...
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.

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.
The IOC has relied heavily on the passport as an ultimate determinant of an athlete’s gender, but Adams allowed, in response to a question from Yahoo Sports, that there is a possibility that ...
The term "gender reveal" is considered a misnomer by those who believe in a distinction between sex and gender. [2] In this view, gender is a social construct and impossible to determine from biological characteristics. Thus, when the "gender reveal" is made, it is the sex and not the gender that is being revealed.
