Inherited Traits
A trait is any characteristic or feature of an organism.
*Such as shape, size, color, etc.
Inherited traits are passed from parents to offspring
(children).
Inherited traits are passed to offspring by all living
organisms- plants and animals.
Some inherited traits are easy to see, such as eye color, hair
color, height, or facial features.
Other inherited traits affect structures inside the body and
cannot be seen, such as bone structure and blood type.
(Think invisible= can’t be seen but it is there)
Not all traits are inherited.

out, however; his/her offspring will not inherited
