My test results don match any others. Does that mean I am not a Caperton?
Q1. What is this DNA test? There are two types of tests now available for genealogical testing. The Y Chromosome (Y-DNA) test and the mitochondrial mtDNA) test. A direct female line can be traced by testing mitochondrial DNA. However, since we are presently interested in tracing surnames, which are usually passed from father to son, testing of the Y-chromosome DNA is what we are interested in. The portion of the Y-Chromosome that is tested for genealogical purposes is passed through the direct male line (father to son) unchanged (other than having an occasional mutation). Human sperm and egg cells contain 23 chromosomes. The 23rd chromosome is the one that determines the sex of the child. Males have an X and a Y 23rd chromosome, while the female has 2 X’s with no Y’s. The human egg becomes a female embryo if the male sperm carries an X-chromosome and a male embryo if the sperm carried a Y-chromosome. Males pass their Y-chromosomes or “DNA fingerprints” down to their sons with little if
