Is It Better To Test With A Grandmother Or A Grandfather?

Category: Grandparent DNA Testing

If the child at question is a male, and the grandfather is available, we suggest you test male to male. When testing 2 males for a relationship DNA test, they have the extra advantage of including Y chromosome testing, if it is necessary. Y chromosomes are an exact match down the male lineage.

If the grandfather is not available, the lab makes the necessary adjustments to test a grandmother and possible grandson.
If the child at question is a female, a DNA test can be done with the grandmother or a DNA test with the grandfather, as either will be sufficient in almost all cases.
