MAAP Science Review

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
