Inheriting DNA Traits Not Inherited Plants 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. The 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. First paragraph pg. 170 Second paragraph pg. 171

Adaptations A 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 Adaptations Structural 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.
