Science Maternity Testing

Well, we seem to have a bit of a question here.
While some cover is being created, if I were a woman accused of claiming my daughter’s child was my own, and I knew such accusations were false, I’d use science to prove myself right.
Using genetics to test for maternity is no different than in paternity testing, and I wrote about that a bit ago:
Paternity testing is all about mixing and matching.
DNA-based tests work by comparing the recipes—the alleles—you have for a given gene to those of a possible child. For most genes, we get two alleles—one from our mother and one from our father. A child of yours must have one of your alleles for all the paired genes in his or her DNA.
A graphic if this process—how genetics can be used to rule out a woman as the mother of a child—is over at dearscience.org.
