A version of a gene that gives different traits, such as eye color, is called this.
What is an allele?
200
A mutation that has no effect on survival or reproduction is called this.
What is a neutral mutation?
200
An inherited characteristic that helps an organism survive and reproduce is called this.
What is an adaptation?

This is what GMO stands for.
What is "genetically modified organism"?
200
This layer of Earth is made of hot, flowing rock beneath the crust.
What is the mantle?
300
The complete set of an organism’s genetic material is known as this.
What is the genome?
300
Sickle cell disease, which causes blood flow problems in humans, would be categorized as this type of mutation.
What is a negative mutation?
300
Predators, climate, or food supply are examples of these, which drive natural selection.
What are selective factors?
300
This plant has famously been modified by humans to ripen slower, allowing it to be picked while green and transported large distances to the market.
What are tomatoes?
300
This cell structure is called the “powerhouse of the cell” because it produces energy.
What is the mitochondrion?
400
If there are two alleles in a person's genome that both determine the same trait, the allele that "wins" and decides the trait is called this.
What is dominant?
400
A mutation that causes an animal to be stronger and faster than all of it's peers, but makes it impossible for this animal to reproduce, would be this kind of mutation.
What is a negative mutation?
400
A chameleon changing color to hide is an example of this type of adaptation.
What is a structural adaptation?
400
This is the replacement or removal of non-functioning genes by the addition of new genes to a patient's genome.
What is gene therapy?
400
This type of consumer eats only plants and includes animals like deer and rabbits.
What is an herbivore?
500
This process makes exact copies of DNA before a cell divides.
What is DNA replication?
500
This mutation in the human genome allowed humans to process cow milk and it's byproducts.
What is lactose tolerance?
500
If a pigeon developed the ability to drink pool water to allow it to survive in a human dominated environment, that would be considered this type of adaptation.
What is a functional adaptation?
500
This type of DNA is created by injecting useful parts of human DNA into bacteria.
What is recombinant DNA?
