ANCESTRY REPORT
Genetic ancestry testing. in which genetic data are used to estimate the geographic origins of a person’s recent ancestors, has grown rapidly in popularity.
A recent estimate indicates that more than 26 million people worldwide have undergone genetic ancestry testing by direct-to-consumer (DTC) companies. These tests provide information about an individual’s ancestral roots, and they can help to connect people with their relatives, sometimes as distantly related as fourth or fifth cousins. Such information can be particularly useful when a person does not know their genealogical ancestry (eg. many adoptees and the descendants of forced migrants).
Increasingly and not without controversy, genetic ancestry testing is being used beyond its original purpose, for example, to help identify or exclude criminal suspects.2 In the clinical setting, persons may share their ancestry test results with their clinician with the expectation that the results will inform health care decisions.
How it works
Genetic ancestry testing involves the comparison of a large number of DNA variants measured in an individual with the frequencies of these variants in reference populations sampled from across the world.
In this way, considering different aspects of gene-nutrient interaction and designing appropriate diet for every specific genotype that optimize individual health, diagnosis and nutritional treatment of genome instability, we could prevent and control conversion of healthy phenotype to diseases.

ANCESTRY REPORT
Genetic ancestry testing can provide insights on the geographic origins of an individual’s ancestors, as well as some information that can aid in assessment of risk for some heritable conditions.
What is Genetics?
Humans are made up of cells
Cells consist of nucleus
The nucleus is made up of chromosomes
Chromosomes are made up of DNA
DNA is made up of genes
Genes are encoded by nucleotides
Changes in nucleotides lead to genetic variations
What is Predictive Genetics?
Genetic variations make us all unique
Population prone to curly hair
Population prone to blue eyes
Population at high risk of obesity
Population at high risk of heart attack
