Content of interest for One-Name Studies:

A Y-DNA test is the perfect companion to a one-name study.

Only males have a Y-chromosome. The Y-chromosome is passed from father to son, typically unchanged. In most cultures, this is the same path as the surname.

A male inherits the Y-chromosome from this father, and an X chromosome from his mother. The XY combination makes him a male. A female has two X chromosomes, one from her father, and one from her mother.
