What Is Physical Traits - Others are acquired through learning. The phenotype is what is visible, while the genotype is the underlying gene combination in our dna that actually determines what is expressed physically in the phenotype. Web in biology and genetics, this external expression (or physical characteristics) is called a phenotype. Even though we share some characteristics with our peers and our family members, every one of us has a unique combination of traits. And all of these traits emerged before humans began domesticating plants and animals. A rapid increase in brain size occurred before early humans began using symbols to communicate. Some traits are controlled by genes that pass from parent to child. For example, early humans began walking upright before they began making tools. Web physical traits are unique, observable features that define an individual’s appearance. Web there were important milestones along the way.
