Multiple Choice

The passing of traits from parent to offspring 

• Heredity 
• Genetics 
• Hybrid 
• Probability 

Multiple Choice

one set of instructions for an inherited trait

• heredity
• allele
• trait
• gene

Multiple Choice

The purpose of selective breeding is to

• Get bigger animals and plants

• Get smaller animals and plants

• Create animals and plants with desirable traits

• Create animals and plants with bad traits

Multiple Choice

Which statement best describes a hybrid?

• Breeding two different organisms for a desired trait.

• An animals that can run fast.

• A really big plant.

• An unusual animal.

Multiple Choice

All of the following statements are reasons for selective breeding except:

• To produce offspring with desirable characteristics
• Farmers increase their profit by improving crops
• To improve the quality of food products
• To increase migration patterns

Multiple Choice

Another name for Selective Breeding is

• Evolution

• Natural Selection

• Extinction

• Artificial Selection

Multiple Choice

Evidence shows that the wolf is the ancestor to all of the breeds of dogs shown below. How did this variation arise in a relatively short period of time?

• Genetic manipulation

• Natural selection

• Random chance

• Selective breeding

Multiple Choice

Which statement best describes artificial selection/selective breeding?

• A person choose what will breed. Breeding for a desired trait.

• Survival of the fittest.

• Eat or be eaten.

• Changes over time.

Multiple Choice

Which is an example of SELECTIVE BREEDING ?

• A giraffe’s long neck.

• Training a horse to run faster.

• Clipping a horse’s tail so it is not too long.

• Cross breeding a labrador retriever with a poodle.

Multiple Choice

When people pick 2 organisms with DIFFERENT genetic traits to breed,
 so the offspring will inherit the best traits from both parents:

• adaptation
• hybridization
• inbreeding
• natural selection

Multiple Choice

1 As a farmer, I am certain that I could make more money on my crops if I could prevent bugs from eating the fruit before harvest. I cross my best-selling apple with a pear that does not attract insects. The result is an apple that everyone, but the bugs, wants to eat!

• Selective breeding - inbreeding

• Selective breeding - hybridization

• Genetic engineering

• Cloning

Multiple Choice

Breeders can increase the genetic variation in a population by using

• inbreeding.
• mutations.
• hybridization.
• restriction enzymes.

Multiple Choice

HYBRIDIZATION IS EASY AND INEXPENSIVE

• TRUE

• FALSE

Multiple Choice

4 My rose bushes won the "Green Thumb Award" at the local florist contest. I decide to fertilize the plant using the pollen and eggs from the same bush to grow similar flower bushes.

• Selective breeding - inbreeding

• Selective breeding - hybridization

• Genetic engineering

• Cloning

Multiple Choice

9 A dairy farmer relies on milk production by his cows. He has several cows which produce almost double the amount of milk in the same amount of time when compared to other cows on the farm. He decides to breed the high-milk production cows so that trait is passed to offspring.

• Selective breeding - inbreeding

• Selective breeding - hybridization

• Genetic engineering

• Cloning

Multiple Choice

Mating of two closely related animals is:

• dominance

• codominance

• inbreeding

• pedigree

Multiple Select

Are there any benefits of inbreeding?

• Yes, traits can be magnified.

• No, genetic defects are the only result.
