WHAT YOUR GENES TELL YOU
With the sequencing of the Human Genome in 2003 we learned that humans have 3 billion DNA bases (A,T, G, C) distributed in 23 pairs of chromosomes, which are 99.9% similar between individuals and the differences between weight, height, eye or hair color corresponds to only 0.1% of the genome.
The most common type of genetic variation among people are the Single Nucleotide Polymorphisms (or SNPs pronounced ‘snips’).
