Grandpa’s Eyes and Grandma’s Hair: Tracing the Origin of Physical Traits with Genetic Genealogy


4,964 views

DNA is the underlying code for human life. Variations in this code result in the physical diversity observed between humans. While some physical traits are determined by just a few variations, many more are governed by several to hundreds of genes. Also, while we might point to one ancestor as the source of a particular trait, in fact many of our traits are determined by contributions from both our maternal and paternal ancestors. The interactions of these gene alleles and their products result in our unique physical characteristics. With chromosome mapping, we can also trace the origins of some of these traits and characteristics.
