Haplo Test (Y haplogroup)
Analysis of the Y chromosome STR molecular markers provides haplogroup prediction.
Majority of genetic material remains intact over many generations. For thousands of years we have been sharing these parts of genetic material with our ancestors by maternal (mitochondrial DNA) and paternal lineage (Y chromosome DNA).
- The Y chromosome has only 60 mega bases and, compared to other chromosomes, contains the smallest number of genes and is rich in repeting DNA sequences of all kinds. Since it is inherited paternally, Y chromosome is present only in men and in only one copy.
- In population genetics and forensics, a simultaneous analysis of a number of Y-STR markers (short tandem repeating sequences of DNA Y chromosome) is often performed. Resulting Y-STR profile is called the Y-haplotype. A group of similar haplotypes that share a common ancestor is called a haplogroup. Almost all European men belong eleven Y haplogroups.
Why to get tested?
Y Chromosome Testing provides information based on which further patrilineal research can reveal comprehensive overview of the certain events, for example, the information obtained can help with research of:
- ancient migration routes paternal ancestors may have taken
- living relatives with similar Y chromosome
- identification of surname lines
How does DNA testing for determining Y haplogroup work?
The test is performed by DNA analysis from a buccal swab sample and the test is 100% effective.
The sampling procedure is painless and it takes only 10-15 seconds. 23 molecular Y-STR molecular markers are analyzed. The result is Y-STR profile and information about predicted haplogroup.
