Inheritance and Variation of Traits LS3.A: Inheritance of Traits characteristics of organisms are inherited from their parents. (3-LS3-1) characteristics result from individuals’ interactions with the environment, which can range from diet to learning. Many characteristics involve both inheritance and environment. (3- LS3-2) LS3.B: Variation of Traits organisms vary in how they look and function because they have different inherited information. (3-LS3-1) environment also affects the traits that an organism develops.
