Which is another term for selective breeding?

• Artificial selection
• Natural Selection
• Intelligent selection

Evidence shows that the wolf is the ancestor to all of the breeds of dogs shown below. How did this variation arise in a relatively short period of time?

• A.  Genetic manipulation
• Natural selection
• Random chance
• Selective breeding

The purpose of selective breeding is to

• get bigger animals

• get smaller animals

• create animals with desirable traits

• create animals with bad traits

What is an example of artificial selection?

• Letting dogs choose their own mate

• Letting plants pollinate on their own

• Crossing a labrador and a poodle to create a labradoodle

1. Artificial selection has been a big factor in the evolution of:

• Dogs

• Panda bears

• Snakes

• Jellyfish

A farmer has bred his pineapple plants from the sweetest pineapples from his last harvest to get even sweeter pineapple plants. What is this an example of?

• Selective breeding
• Natural selection
• Extinction
• Mutagenesis

These cause variations.

• mutations
• adaptations
• a desire to change
• injuries

A slight difference in an inherited trait between individual members of the same species.

• variations
• adapatations
• homologous structures
• analogous structures

An inherited trait that increases an organism's chance of surviving and reproducing.

• variation
• adaptation
• vestigial structure
• mutation

Adaptations can be:

• camouflage

• ability to survive cold weather

• hunting skills

• all of the above
