Scientists call the path that electricity takes an electric circuit. Electric circuits are used to carry electricity to places where we can use it. At home, at school, in factories or anywhere that relies on electricity. The electricity is carried to where it is needed by wires.
trait. A characteristic or condition that is determined by one's genes. The color of an animal's coat and the shape of a plant's leaves are physical traits.

We represent these gene pairs by writing a combination of two capital or lowercase letters. trait is a characteristic such as color or size that is inherited by an offspring from its parents.
