 Tip of the week: Resellers vs. Laboratories. Why do DNA tests range from $140 to $800? The difference is this: Many online companies are resellers that act as middle-men. They purchase test kits from larger laboratories, and resell them at a higher price to gain a profit. Always ensure that your laboratory is AABB and ISO accredited and has a physical address

Y-Chromosome testing can trace the male lineage and is a very useful test for genealogists as well as males who need to know whether they are related along the male line. All males have a Y chromosome (females do not have a Y-chromosome). A male's Y-chromosome is passed down to him directly from his father, and his father inherited his y chromosome from his father. The Y-chromosome is passed down relatively unchanged from a male to all of his sons, and his sons pass it down to all of their sons and so on. The Y-chromosome test has many powerful applications.
Determination of whether two or more males are related The Y-chromosome test is useful for males who need to find out whether they are related to another male along the male lineage. For example, a grandson and his grandfather will have the same Y-chromosome. A nephew will have the same Y-chromosome as his uncle (father's brother), as well as all of his uncles sons (male cousins). A male will have the same Y-chromosome as all males which have the same common male ancestor as himself. Thus, this test is very powerful for deterimining distant relationships, and helps to solve the question of whether two males are related along the male line. Solve ancestry questions for genealogists Because the Y-chromosome is passed down along the male line, the same way that the surname is passed down from a father to all of his sons, Y-chromosome testing is a very useful tool for genealogists who are interested in tracing their surname. The Y-chromsome test is able to help genealogists gain definitive answers when they reach a point in their research where they do not have paperwork to establish a family link, or if they need to prove a hypothesis. Genealogists can now order their Y-chromosome test directly from our ISO accredited testing laboratory without having to pay marked up pricing through a genealogy testing reseller.
