From Wolf to Woof Intro to Genetic Engineering

Natural selection

Genetic mutation

Selective breeding

Random mating

Selective breeding

Genetic engineering

Both selective breeding and genetic engineering

Neither selective breeding nor genetic engineering

Selective breeding involves choosing organisms of the same species to mate, while genetic engineering involves moving genes between different species.

Selective breeding involves moving genes between different species, while genetic engineering involves choosing organisms of the same species to mate.

Both processes involve moving genes between different species.

Both processes involve choosing organisms of the same species to mate.

Because it can affect personal, cultural, and global values.

Because it is always beneficial to society.

Because it only affects animals, not humans.

Because it is a simple process with no consequences.

Taking DNA from one organism and inserting it into another to produce a specific trait

Allowing organisms to develop traits naturally over time

Cross-breeding two organisms to create a hybrid

Using chemicals to change the traits of an organism

Take the gene for making insulin from a healthy donor’s DNA

Add the gene to the DNA of pancreas cells from a diabetic

Let mitosis happen to produce many pancreas cells with the good gene

Surgically implant the good cells back into the diabetic

To make the cabbage taste better

To kill caterpillars that eat crops

To make the cabbage grow faster

To change the color of the cabbage

It can create organisms with traits not previously thought possible.

It can remove 'bad' genes.

It reduces the chance of getting undesirable organisms.

It is inexpensive and does not require special equipment.

Creation of superweeds

Increased crop yields

Natural insecticides getting into soil

Unknown long-term effects

To create offspring with the desirable traits of both parents

To eliminate all undesirable traits

To produce genetically identical organisms

To increase the number of offspring

Santa Gertrudis cattle; good beef and resistant to heat

Brahman cattle; good beef and poor heat resistance

English shorthorn cattle; poor beef and good heat resistance

Santa Gertrudis cattle; poor beef and resistant to heat

Improved organisms

No need for special tools or lab

Can be performed easily by farmers and breeders

All of the above

Undesirable traits may appear in offspring

Disease can accumulate in the population

All offspring will be healthy

Selective breeding always produces improved organisms

Natural selection in the wild

Selective breeding by humans

Random mutations without human influence

Environmental changes only
