Genetic information is stored in DNA. Segments of DNA that encode proteins or other functional products are called genes.
Genes are the basic physical and functional units of heredity. Each gene is located on a particular region of a chromosome. Adenine, thymine, guanine, and cytosine are nucleotides and are the building blocks of DNA. Each gene has a specific ordered sequence of these nucleotides.
A gene can exist in many different forms, called alleles. For example there is a gene which determines the color of hair. That gene may have many forms, or alleles: black hair, brown hair, auburn hair, red hair, blond hair, etc. One allele for each gene comes from the mother and one from the father.
Each of the two inherited alleles for a gene each may be strong (“dominant”) or weak (“recessive”). When an allele is dominant, it means that the physical characteristic (“trait”) it is coded for is usually expressed, or shown, in the living organism. Only one dominant allele is needed to express a dominant trait. Two recessive alleles are needed to exhibit a recessive form of a trait. Researchers investigate just what each gene is responsible for in the human body, and how mutations to genes cause genetic diseases.
The FindWhy™ test identifies DNA variations called single nucleotide polymorphisms (SNP’s) and is based on a detailed analysis of the scientific literature. This test is a risk assessment test and is not a diagnostic test. The test does not guarantee weight loss by following a particular dietary strategy, nor does it provide obvious benefit from choosing one diet over another based on the test results. This test is designed to shed light on an individual’s genetic background, and therefore allow patients to create a weight loss plan that will help overcome possible predispositions, and to help them achieve lasting results.
