What is selective breeding?
Choosing animals or plants with desirable traits to reproduce
Creating identical copies of organisms in a lab
Changing the DNA of an organism directly
Allowing organisms to reproduce randomly
Which process involves making an exact genetic copy of an organism?
Selective breeding
Cloning
Genetic engineering
Natural selection
What is the main goal of genetic engineering?
To produce more offspring
To change the DNA of an organism to give it new traits
To allow organisms to breed naturally
To create identical twins
Which of the following is an example of selective breeding?
Inserting a gene for disease resistance into a plant
Crossing two dogs to get puppies with curly hair
Making a copy of a sheep in a laboratory
Allowing plants to pollinate randomly
What is the name of the first cloned mammal?
Dolly the sheep
Bella the dog
Max the cat
Daisy the cow
Which technique can be used to produce insulin for people with diabetes?
Image: Structure of insulin molecule
Selective breeding
Cloning
Genetic engineering
Cross-pollination
Which of the following is NOT a benefit of selective breeding?
Image: Selective breeding in cows
Producing crops with higher yields 
Increasing genetic diversity 
Creating animals with desired traits 
Improving disease resistance in plants 
What is a possible risk of cloning?
Increased genetic diversity
Reduced genetic variation
Faster growth rates
Improved health
Which process involves transferring a gene from one species to another?
Selective breeding
Cloning
Genetic engineering
Natural selection
Why might farmers use selective breeding?
To create genetically identical animals
To improve crop yield and quality
To change the DNA of plants directly
To increase genetic diversity
Which of the following is a result of genetic engineering in plants?
Plants with genes for drought resistance
Plants with more flowers due to cross-pollination
Plants that are clones of each other
Plants with random genetic changes
What is the main difference between selective breeding and genetic engineering?
Selective breeding changes DNA directly, genetic engineering does not
Genetic engineering changes DNA directly, selective breeding does not
Both change DNA directly
Neither changes DNA
Which method yields the quickest results in changing an organism’s traits?
Selective breeding
Genetic engineering
Cloning
Natural selection
Why does genetic engineering produce results faster than selective breeding?
It allows direct changes to DNA
It relies on random mutations
It takes many generations to see changes
It only works with animals
How does selective breeding change traits in a population?
Image: Selective breeding has led to a variety of dog breeds with different traits.
By making changes in one generation
By slowly changing traits over many generations
By directly editing the DNA
By cloning the best individuals
