Problems with selective breeding include

• Better animals

• Increased meat production

• Animals can have bad health problems

• more diversity

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
