The Pearsall Family DNA – Surname
Project
RESULTS – 43-MARKER TEST
As this family DNA surname project
develops, more information for family member results will be posted.
Individuals will not be identified by name to protect privacy; we will
use surname, location, and a code.
DNA HERITAGE (43-MARKER) RESULTS
Since this project is just starting, I
will share my results so you can have a peek at what you might find. DNA
Heritage provides a comprehensive 43-marker test. The 43-marker test results for myself
are below:
§§§
Higher resolution (43-marker) tests
allows geneticists to infer more detailed views of how Haplogroups are
sub-divided into Haplotypes / sub-clades, all the way down to how closely
individuals are related (within several generations).
The following diagrams illustrate how Haplogroup I can be exploded
into smaller branches or sub-populations:
As more markers are used, ultimately
families and branches within families can be identified. Y-STR markers do not identify
individuals, but groups of individuals (men) that share the same or
similar Y-chromosome.
Note: DNA testing used for forensics or
paternity testing relies on a different type of DNA test called an
Autosomal DNA test. Autosomal DNA
markers can identify individuals; these are generally not used for
genealogy since distant relations to a specific ancestor cannot be
inferred through autosomal DNA testing.
Based on searches in several databases and calculation of genetic
distance, the Pearsall and Lindsay families are closely related families
(e.g. share a common ancestor within ~50 generations):
More to come…
