Artificial Selection Lesson 3 Review

The biological and chemical methods that change the arrangement of DNA that makes up a gene.

• variations

• artificial selection

• genetic engineering

• mutations

Putting a gene for bioluminescence into a fish is an example of ___.

• genetic engineering

• selective breeding

• artificial selection

• gene mutation

Breeders select two parents that have beneficial phenotypic traits to reproduce, yielding offspring with those desired traits.  This is an example of ___.

• artificial selection

• natural selection

• genetic engineering

Santa Gertrudis cattle are a cross between Brahman cattle (resistant to heat) and English shorthorns (good beef).  This is an example of ____.

• natural selection

• genetic engineering

• selective breeding

Farmers raise corn that has been made virus-resistant by adding a gene from the teosinte weed.  This is an example of ___.

• natural selection

• genetic engineering

• selective breeding

The "Flavor Savor" tomato doesn't rot as quickly as a normal garden grown tomato because they were ___.

• going through gene therapy

• selectively bred

• genetically modfied

• changed through natural selection

Artificial Selection decreases diversity which is bad because ___.

• organisms with the same traits will refuse to reproduce with each other

• organisms with all the same traits are susceptible to extinction

• organisms with the same traits will be very aggressive

• organisms with the same traits collectively get smarter and will some day rule the world

Food products that have been genetically modified.

• GDOs

• GFOs

• GMOs

• GTOs

What traits are not selectively bred into fruits and vegetables?

• larger

• fewer seeds

• less expensive

• sweeter

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 and artificial selection, the process takes hundreds of years to occur.

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

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