How does the Grandparent DNA test work?
DNA samples taken from the mouth swabs provided, are used to generate a DNA profile for each test participant. The DNA profiles are compared and statistically analysed in order to determine the likelihood of the tested relationship i.e. the likelihood that the participants are biologically related as full Grandparents, half Grandparents or that they are biologically unrelated.
The Grandparent DNA test is based on the fact that a child inherits half of his or her DNA profile from each of their biological parents i.e. half the child’s DNA profile matches their biological mother and the other half matches the biological father. Due to this, the DNA molecule of full Grandparents and half Grandparents will demonstrate an increased amount of genetic material in common, when compared to the DNA of unrelated individuals.
The Grandparent DNA test not only provides evidence of whether two individuals are related or not, but can provide evidence to what degree those individuals are related i.e. whether the individuals share one biological parent or two biological parents. Please refer to the information leaflet enclosed for detailed information regarding this DNA test.
