Lesson 5- Artificial Selection

A farmer buys a bull that grows really large very quickly to breed with his cows so their offspring can produce more meat. Which type of artificial selection is this?

• Selective breeding

• Inbreeding

• Hybridization

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

The following is a similarity between artificial selection and natural selection

• Takes hundreds of years

• Humans determine traits

• Nature determines traits

• Offspring are produced

Which statement is true comparing natural selection and artificial selection?

• In natural selection, traits benefit humans and in artificial selection, the traits benefit the species

• In natural selection, traits benefit the species and in artificial selection, the traits benefit humans

• In natural and artificial selection, the process takes hundreds of years to occur

• In natural and artificial selection, nature determines what traits will be passed down to offspring.

Artificial selection takes

• a shorter period of time than natural selection

• a longer period of time than natural selection

• the same amount of time as natural selection

Artificial selection is also known as

• natural selection

• selective hearing

• genetic manipulation

• selective breeding

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

• Evolution
• Natural Selection
• Extinction
• Artifical Selection
