Multiple Choice

dominant

• an allele that is masked when a dominant allele is present

• the set of information that controls a trait

• an allele whose trait always shows up in the organism when the allele is present

• when characteristics are passed from parent to offspring

Multiple Choice

heterozygous

• the scientific study of heredity

• the children of an organism

• having two different alleles for a trait

• having two identical alleles for a trait

Multiple Choice

homozygous

• having 2 different alleles for a trait

• characteristic that an organism can pass onto its offspring

• having two identical alleles for a trait

• the study of heredity

Multiple Choice

Which is another term for selective breeding?

• Artificial selection
• Natural Selection
• Intelligent selection

Multiple Choice

An example of selective breeding is

• a dog breeder mating 2 dogs to make more dogs

• a farmer grows bees to pollinate the plants on his farm

• a person pollinates 2 white rose plants to only create white roses

Multiple Choice

Selective breeding is...

• a process to create an organism with desired traits from parents with those desired traits

• natural method of producing offspring with desired traits

• creating a new species

• making organisms reproduce during times of stress

Multiple Choice

How are selective breeding and GMO's different?

• GMO's can impact the environment, Selective breeding can not

• GMO's have been happening for thousands of years, Selective breeding is a new practice

• Selective Breeding occurs over several generations, GMO's are produced rapidly in the lab

• Selective breeding occurs in only plants. Both plants and animals can be genetically modified

Multiple Choice

What is NOT a reason to genetically modify plants? 

• To make the plants poisonous to insects
• Make plants drought resistant 
• To produce fewer plants
