• The process of an organism passing on their worst traits to their offspring.

• The process of an organism passing on their best traits to their offspring.

• The process of an organism passing on their strangest traits to their offspring.

What are the two types of adaptation?

• Structural and Fragmental

• Structural and Behavioral

• Adaptive and Adaptation

• Behavioral and Fragmental
