Selective breeding is...

• a process to create an organism with desired traits from parents with those desired traits

• natural method of producing offspring with desired traits

• creating a new species

• making organisms reproduce during times of stress

An example of selective breeding is

• a dog breeder mating 2 dogs to make more dogs

• a farmer grows bees to pollinate the plants on his farm

• a person pollinates 2 white rose plants to only create white roses

One problem with selective breeding is

• creating a new species

• gene variety is lost

• extinction of a species

Which of these is the first step in selective breeding flowers.

• Repeat the process only with the offspring with the desired traits

• watch the seeds grow

• Choose plants that have the desired trait to pollinate

• chose which trait is desirable

The purpose of selective breeding is to 

• Get bigger animals
• get smaller animals
• create animals with desirable traits
• create animals with bad traits

All of the following statements are reasons for selective breeding except:

• To produce offspring with desirable characteristics
• Farmers increase their profit by improving crops
• To improve the quality of food products
• To increase migration patterns

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

"Survival of the fittest" describes which theory

• Natural selection

• Selective breeding

The long and sharp beak of a woodpecker is an example of

• natural selection

• selective breeding

Natural selection is where ___________ decides which traits should be passed on.
