DNA testing to determine your family history
Genealogical DNA testing is used to determine your
family history, ancestral make-up or the country of origin.
What
Is DNA?
Everyone’s DNA structure is unique and it is formed by
46 chromosomes at the time of conception. It may similar for identical twins
but not for anyone else. Once formed, it won’t change throughout the life. Each
individual carries a special genetic molecule called as mitochondrial DNA and Maternity DNA test (mtDNA) which is inherited entirely from mother’s side. DNA test contains an
analysis of mtDNA or Y-chromosome which is exclusively inherited from a
biological father in case of a male child.
What
Is Genealogical Testing?
A genealogical
DNA test inspects the nucleotides at specific locations for genetic
genealogy purposes on a person's DNA. It is not carried out to collect
informative medical value nor a genetic disease or disorder. It is meant to
provide only genealogical or personal ancestry information.
It is carried out using cheek swab rather than a blood
sample. Cheek swab tests results are accurate as it would be taken through a
blood sample.
What
Can Genealogical Testing Do?
It is used to discover the paternal line origin by
analyzing genetic markers. It is also used to discover maternal origin using
mitochondrial markers. Genealogical DNA
testing is generally carried out to determine your family history whether
your ancestry comes from different continental level such as European, African,
Asian, etc.
If anyone is interested to find out recessive gene
variants for blue eyes you carry, your DNA can be tested for various gene
variants. It will give you probability whether there are weak or strong chances
to have blue eyes children.
If you are carrying out genealogical DNA testing, it would be recommended to check the
testing laboratory whether it is accredited to provide results as per
recognized standards at international level. If you want the most accurate
results for genealogical DNA testing
