Multiple Choice

Selective breeding is...

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

• natural method of producing offspring with desired traits

• creating a new species

• making organisms reproduce during times of stress

• Any change in the physical features of a human

• A change in the DNA sequence

Multiple Choice

Which of the following best represents inbreeding?

Multiple Choice

Scientists genetically engineer corn to be immune to corn diseases. This is BENEFICIAL because

• This causes corn to be less likely to reproduce
• This causes corn to be less likely to survive
• This causes corn to be smaller
• This allows increased production of corn
