	The second method uses your haplogroup with your STR marker results. These are used to match you to others. These matches are more likely to share your line in historic times. Country frequencies thus reflect your ancestors’ recent history. Both the Y-DNA – Haplogroup Origins and the Y-DNA – Ancestral Origins pages show this information.

	The first method uses your main (backbone) branch on the paternal tree. This is your Y-DNA haplogroup. Scientists study the history of populations across geography and time using Y-DNA. They use both the frequencies of each branch in modern populations and samples from ancient burial sites. With these, they are able to tell us much about the story for each branch. This traces back hundreds, thousands, or even tens of thousands of years. Your branch on the tree tells you where your paternal ancestors are present today and about their likely migration paths.

	Your Y-DNA may help you find genetic cousins along your direct paternal line. For Y-DNA37 results, ~~we report~~ your results for STR markers. STR marker values change slowly from one generation to the next resulting in distinctive sets of results. ~~We compare your~~ set of results to those of other men ~~in our database~~. The range of possible generations before you share a common ancestor with a match is wide. Your Y-DNA37 exact matches (0 Steps) may be recent, but they may also be hundreds of years in the past. Your matches that have one marker difference (1 Step) may be even more distantly related. ~~We show this~~ in the table below.

	Your Y-Chromosome is a sex chromosome. Sex chromosomes carry the genetic code that makes each of us male or female. All people inherit two sex chromosomes. One comes from their mother and the other from their father. You and other men receive a Y-Chromosome from your father and an X-Chromosome from your mother. Men and only men inherit their father’s Y-Chromosome. Thus, it follows the same path of inheritance as your direct paternal line.		Your Y-Chromosome is a sex chromosome.

	STR markers are places where your genetic code has a variable number of repeated parts. ~~We report your~~ STR marker results as the measured number of repeats for each marker.

	Over many generations, the number of repeats in each STR marker changes. The number of repeats may go up or down. These changes create the patterns (haplotypes) of individual lines. This process is random. It is not possible to predict that any one marker will change between any set of generations. We do know though how often on average these random changes happen. Thus, we can estimate how closely related two men are by using the similarity of their results.		Over many generations, the number of repeats in each STR marker changes.
