Movement of alleles between 2 populations is called:

• genetic drift
• gene flow
• mutation
• natural selection

Match the following:

• 
• Robins have 4 eggs, seldom more or less.

• 
• Pocket Mice on black rocks and tan sand.

Mutations:

• Happen when a species needs them.

• Happen when the environment changes.

• Happen randomly, all the time.

• Happen to individual organisms that need them.

Match the following

• Survival of the Fittest

• The individuals with variations that help them in the current environment are more likely to survive long enough to pass on their genes.

• Creates different alleles. Mutation.

• Errors in copying DNA during cell division or damage repair.

• Mutation

• Scientific theory

• Science's highest level of certainty

• The name of changes that create different alleles.

• The whole set of different genes available to and shared by a population.

• The subset of genes that only individuals with helpful mutations gets.
