How can mutations change the genetic makeup of an organism?

• By helping the organism adapt to a new environment
• By changing the organelles that make up a cell 
• By changing the DNA that makes up a gene
• By copying the DNA that makes up a gene

Scientists used selective breeding to produce a population of foxes that are less aggressive than wild foxes. Which statement best describes how selective breeding allowed scientists to produce less aggressive foxes?

• Selective breeding created alleles for nonaggressiveness by combining genes from foxes and another species.
• During selective breeding, less-aggressive foxes that had traits that allowed them to survive were more likely to have offspring.
• Selective breeding created alleles for nonaggressiveness by encouraging mutation of genes.
• During selective breeding, scientists chose less-aggressive foxes to have offspring.

How may selective breeding change the genetic makeup of an organism?

• The breeder controls which traits are passed on
• The breeder implants DNA into the organism
• The breeder takes out DNA from the organism
• The breeder allows the organisms to reproduce freely

How does biotechnology change the genetic makeup of an organism?

• By cloning or producing life in a laboratory
• By altering an organism's DNA
•  By breeding organisms with favorable traits
• By using mutations in organisms to produce desired results

Which of the following is NOT a way that humans use biotechnology?

• Producing new metals 
• Producing more food
• Cloning animals
• Producing fuel from plants

How is selective breeding different than biotechnology?

• Selective breeding deals with organisms, biotechnology doesn’t
• Selective breeding can improve crops, biotechnology doesn’t
• Selective breeding changes genetics of organisms, biotechnology doesn’t
• Selective breeding changes genetics through breeding, biotechnology doesn’t
