Ancestry research Rittmeier / Rittmeyer

The following project members have registered for a DNA test on the genealogy portal FamilyTreeDNA and also performed a Y-test to determine their respective haplogroup.

The Y chromosome is the male sex chromosome. The DNA of the Y chromosome (yDNA) is inherited only from the father to the son and therefore allows conclusions about the relationship in the direct, purely male line. The determination of the so-called haplogroup allows conclusions about the geographical origin of the purely male line in the last millennia (Source: GenWiki).

It follows that subjects with different haplogroups from the outset can not be related to each other (except in illegitimate births, where ancestors have continued the family name of the mother).

In order to be able to determine a relationship on the paternal line, it is additionally necessary to determine the genetic density of the individual subjects with the same haplogroup. The evaluation below in FamilyTreeDNA shows, for example, a sorting by haplogroups and thus allows an evaluation of the relationship based on the genetic density. Therefore, in the hitherto tested subjects a relationship between 2 subjects in the haplogroup "I-M170" and 4 subjects in the haplogroup "R-M269" can be unequivocally confirmed on the basis of the genetic density.

These evaluations were carried out for subjects who have registered with FamilyTreeDNA for the surname project RITTMEIER / RITTMEYER and have performed a Y-test (at least Y-37).
