Selective breeding and natural selection

Selective breeding is...

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

• creating a new species

• natural method of producing offspring with desired traits

• making organisms reproduce during times of stress

Increasing helpful traits to an organism is one way a breeder may use selective breeding.

• True

• False

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

Selective breeding

• organisms better adapted to their environment tend to survive and produce more offspring

• process used by humans to develop new organisms with desirable characteristics

An example of selective breeding is

• a dog breeder mating 2 dogs to make more dogs

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

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

What is one of the processes involved in selective breeding?

• allowing organisms to reproduce without interference

• choosing individuals with desirable characteristics to be parents of the next generation

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

• Extinction

• Natural selection

• Mutagenesis

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution

• Extinction

• Natural Selection

• Artifical Selection

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.

• Because they come from recessive alleles.

• Because they come from dominant alleles.

• Because the trait is an acquired phenotype.
