What is Dominant
Definition: scientist responsible for the theory of evolution/natural selection
Who is Charles Darwin
Definition: theory that states organisms which are better adapted to their environment are more likely to survive and reproduce than other organisms
What is Natural Selection
On a pedigree, what symbol are males represented by? A female
What are Squares (males) and circles (females)

In humans, straight hair (H) is dominant over curly hair. If two heterozygous parents have children, what is the probability their offspring will have curly hair?complete the punnett square to find your answer. What is the probability of straight hair?
What is 25% Curly and 75% straight
Definition: body parts that are found in living organisms but have no purpose today

Explain the difference between behavioral adaptations and physical adaptations.
What is Behavioral adaptations are how the person acts or what the person do and physical is what he looks like.
