-
Height: Genetic factors play a significant role in determining an individual's height, with multiple genes contributing to this trait.
-
Risk for certain diseases: Certain genes are associated with an increased risk for various diseases, such as cancer, heart disease, and diabetes. Specific genetic variants can influence an individual's susceptibility.
-
Hair color: Hair color is largely determined by genetic variations, particularly in genes that regulate the production of melanin.
-
Eye color: Similar to hair color, eye color is influenced by multiple genes that determine the pigmentation of the iris.
In summary, DNA can code for a wide range of traits, including physical characteristics and predispositions to health conditions.
