From Wolf to Woof Intro to Genetic Engineering

Open Ended

How did we get from a wolf to a chihuahua? These two animals belong to the same species. How can humans create such extreme differences in size, shape, and behavior?

Multiple Choice

Which process is primarily responsible for the wide variety of dog breeds seen today?

• Natural selection

• Genetic mutation

• Selective breeding

• Random mating

Multiple Choice

Which of the following activities are considered controversial according to the lesson?

• Selective breeding

• Genetic engineering

• Both selective breeding and genetic engineering

• Neither selective breeding nor genetic engineering

Multiple Choice

What is the main difference between selective breeding and 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.

Multiple Choice

Why might genetic engineering be considered an ethical issue that requires regulation?

• 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.

Open Ended

Discuss the advantages and disadvantages of both selective breeding and genetic engineering.

Multiple Choice

Which of the following best describes genetic engineering?

• 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

Multiple Select

Which steps are involved in giving the insulin gene to diabetics using genetic engineering?

• 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

Open Ended

Explain how genetic engineering can be used to help people with diabetes, based on the example provided.

Multiple Choice

What is the purpose of adding a gene for producing scorpion venom to cabbage plants?

• 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

Open Ended

Describe how genetic engineering can help tomatoes grow in cold weather.

Multiple Choice

Which of the following is NOT an advantage of genetic engineering?

• 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.

Multiple Select

Which of the following are potential negative environmental impacts of genetic engineering?

• Creation of superweeds

• Increased crop yields

• Natural insecticides getting into soil

• Unknown long-term effects

Open Ended

Explain one ethical issue that may arise from the use of genetic engineering.

Multiple Choice

What is the purpose of mating organisms with different desirable traits in selective breeding?

• 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

Multiple Choice

Which cattle breed is produced by crossing Brahman cattle and English shorthorn cattle, and what are its advantages?

• 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

Open Ended

Explain how selective breeding led to the improvement of corn crops over thousands of years.

Open Ended

Describe how selective breeding was used to produce the big red tomato shown in the image.

Multiple Select

Which of the following are advantages of selective breeding?

• Improved organisms

• No need for special tools or lab

• Can be performed easily by farmers and breeders

• All of the above

Multiple Select

What are some possible disadvantages of selective breeding in animals?

• Undesirable traits may appear in offspring

• Disease can accumulate in the population

• All offspring will be healthy

• Selective breeding always produces improved organisms

Multiple Choice

Which of the following is the main reason for the wide variety of dog breeds seen today?

• Natural selection in the wild

• Selective breeding by humans

• Random mutations without human influence

• Environmental changes only
