Basic Genetics

Heredity is when genes, such as personality or physical traits are passed down from another generation to you. Traits are features that a person may have. Some examples are brunette hair, hazel eyes, or being short. Those are physical traits. I learned that sometimes our environment can change our traits. I also learned about single-gene traits and complex traits. Single-Gene traits are when only one gene is shaped by a trait. Complex traits are when traits are influenced by more than one or many genes. Before today I didn't realize how complicated heredity and different traits can actually be.
