The warrior gene

The MAOA-L gene variant, the so-called warrior gene, causes its carriers to be more willing to take risks while simultaneously enabling them to better assess their chances of success in critical situations. For a recently published study, scientists at the California Institute of Technology pitted 83 young men against one another in a financial simulation. This entailed them having to gamble and multiply their seed money, USD 25, in different games. Each man had to choose between a sure option (100% no profit, no loss) and a risky option (various risks of loss and chances of profit) 140 times. The findings of the study: carriers of the MAOA-L gene variant were more prone to take financial risks, but only if doing so was beneficial to them. This indicates that carriers of the warrior gene variant are in a better position to make decisions, which are beneficial to them. Earlier studies have shown that the MAOA-L variant can also be responsible for impulsive behaviour and aggressive behaviour, which is why this variant was given the nickname warrior gene. Human behaviour is complex and affected both by genes as well as by the environment or circumstances. Studies show that carriers of the warrior gene variant more likely show the described behaviour than men without the warrior gene variant. The warrior gene is on the X-chromosome; hence, men inherit it from their mother. Since men have only one X-chromosome, the warrior gene is fully effective if present. In contrast, women have two X-chromosomes, which is why one single warrior gene either has no or less effect. The effect of the warrior gene on a woman if she has it on both X-chromosomes has yet to be established. The warrior gene test is available for men and women.

Ancestry research

Find relatives across the entire world with a DNA-test and research the origin of your ancestors.

To search for relatives you will receive a list of persons who share your genetic profile in the pure paternal and female lineage in your online-result. You can contact them by email and exchange data. In the surname projects different persons and lineages with the same or similar surnames are compared.

This customer has uploaded a pedigree as a gedcom file which you can compare with your own data.   Click on this symbol to receive a calculation about the closeness of the kinship with your genetic cousin.

With the help of the Family & Population Finder you will additionally receive a list of relatives from all ancestral lineages. Beside the name and email address also the assumed degree of kinship is mentioned and also a list of surnames of all ancestors of this person.

Haplogroups

Haplogroups can be compared with huge branches of the human family tree. A haplogroup unites people with a similar genetic profile who share a common ancestor. A Y-chromosome haplogroup contains men who share a common ancestor in their pure male ancestral lineage. The Y-chromosome is passed on from father to son. A mtDNA haplogroup contains men and women who share a common ancestor in their pure female ancestral lineage. The mtDNA is passed on from a mother to her children.

Migration of the Haplogroups K (Y-DNA) and A (mtDNA).

Region of origin

The Region of origin shows the area in which your profile is typical. This area is usually declared as a bigger region like Western Europe. As far as possible also a more definite core area, like France, is declared.

Ancient tribes

By ancient tribes, we refer here to people groups from Antiquity who are defined not only by their own language, culture and history but also by their own DNA-profile. What is important is not the common linguistic ancestry or the historical-anthropological categorization, but the genetic characteristics of a tribe.

Example: Jews The tight connection of culture, tradition, religion and ethnicity evinces itself especially among Jews. Jews developed over the centuries a certain degree of genetic homogeneity that becomes visible in a DNA-test. » Jews

Example: Vikings By analyzing blood samples from Northwest England that are more than 1,200 years old, so-called "Viking Blood" could be isolated. Geneticist David Goldstein carried out the analysis which discovered certain genetic markers that are indicative of Viking ancestry. In order to confirm the results of the research, more than 2,000 saliva samples from Scandinavia were compared. The test subjects came from specific regions that are still recognized as Viking settlements today. » Vikings

DNA-profile

Your DNA-profile is used for the comparison with other costumers. The more similar two profiles are, the closer is the kinship between the two people. The additional comparison with data from studies and several databases is relevant for the analysis of origins. The bigger the profile the more significant are these comparisons.

Y-DNA-profile A Y-DNA-Test analyses a certain number of markers (12, 37, 67). These are positions on the Y-chromosome. This chromosome is always passed on from father to son.

Locus   1 2 3 4 5 6 7 8 9 10 11 12 DYS#   393 390 19* 391 385a 385b 426 388 439 389-1 392 389-2 Allele   13 24 14 11 11 14 12 12 12 13 13 29

mtDNA-profile A mtDNA-Test analyses certain regions on the mitochondrial DNA. These regions are called HVR1 and HVR2. The mtDNA is always passed on from a mother to her children.

HVR1 differences 16519C   HVR2 differences 263G, 309.1C, 315.1C

Due to its length a mtDNA-profile is only shown as far as it differs from the so called Cambridge Reference Sequence (CRS), a mtDNA-profile that all mtDNA-profiles worldwide are compared to.

Paternal lineage

The paternal lineage is the pure male lineage including the father, the paternal grandfather, his father and so on. All men of the same paternal lineage share the same Y-chromosome.

This test analyses 37 markers of the Y-chromosome.

Including participation in the Genographic Project.

Note: The test for the paternal lineage can only be ordered for a male test person. Women can analyse her paternal lineage with the help of a male relative.

Maternal lineage

The maternal lineage is the pure female lineage including the mother, the maternal grandmother, her mother and so on. All persons of the same maternal lineage share the same mtDNA.

Family & Population Finder

With the Family Finder test you may extend the power of genetic genealogy to all of your ancestors. Using a test of your own DNA, you can discover connections to descendants of all sixteen of your great-great-grandparents. In your online-result you will receive a list of matches that is designed to be quickly sorted to allow you to focus on your near or distant cousins. Because email addresses are provided for easy communication with your near or distant cousins you will be able to share research easily.

The PopulationFinder determines the percentages of different ancestries that comprise your genetics by matching your autosomal DNA against data from multiple populations.

iGENEA basic best price guarantee

iGENEA guarantees that you will not find the same DNA analysis cheaper anywhere else. We will refund you with twice the difference if you find an equivalent test that can be bought cheaper elsewhere within 30 days of ordering your test.*

* The best price guarantee applies to DNA tests with the same scope, e.g. 12 marker or HVR1 analysis, and postage costs. Special offers are excluded.

Surname projects

A surname project is a great way to combine traditional ancestry research with DNA genealogy. In a surname project, an investigation of the biological relationship between men with the same or similar surnames is conducted. This is especially helpful if the common ancestor lived at a time in which surnames already existed, but for which no written records have survived.
