Study Notes
Heredity
- Heredity refers to the process by which traits and characteristics are reliably inherited from one generation to the next.
Inherited Traits
- A child bears all the basic features of a human being, but does not exactly resemble its parents.
- Human populations show a great deal of variation.
Earlobe Types
- Earlobes can be classified as free or attached.
- The type of earlobe a person has can be correlated with that of their parents, suggesting a possible rule for the inheritance of earlobe types.
Inheritance of Traits
- The rules of heredity determine how traits are inherited from one generation to the next.
- Traits can be influenced by the genetic contribution of parents.
