Genetic recombination

... individual genes, as each chromosome may contain genetic information from two different chromatids. Recombination results in a new arrangement of maternal and paternal alleles on the same chromosome. Although the same genes appear in the same order, the alleles are different. This process explains why ...

Paternity testing

... that based on the nuclear genome. However, testing the mitochondrial genome can only prove if two individuals are related by common descent through maternal lines only from a common ancestor and is thus of limited value (for instance, it could not be used to test for paternity). Obtaining news that a ...
