Inheriting DNAPlants and animals inherit half of their genes or DNA from each parent, which decides almost everything about how an organism grows.

Every animal is different since we get a mix of genes, but are similar because they have two eyes and one nose, ect.

Traits Not InheritedThe environment also plays a role with certain traits in animals, like the snowshoe hares fur turns white in the winter so that it can hide better in the snow.

AdaptationsA change in an organism’s genes that can be passed from parent to offspring is called mutation, which can be helpful, harmful or neither.

Organisms with adaptations to compete for limited resources may survive and pass their genes to their offspring.

Structural Adaptations Behavioral AdaptationsStructural adaptations are changed body parts that help an organism live in its environment.

A bird’s beak might be of different shapes depending on what food it needs to get.A male lion’s mane makes him look bigger and protects his neck.

Behavioral adaptations are inherited behaviors that help animals survive.

Bees and ants are born with instincts that help them work together in their habitat.Lions do not know how to hunt when they are born, but the parents teach the cub how to hunt and find food to survive, making it a learned behavior.
