Dominant/Recessive Traits
This term describes two different alleles for the same gene.
What is Heterozygous?
A change in the DNA sequence of a gene.
What is a Mutation?
Male and Female reproductive cells
What are Gametes?
The process in which organisms with helpful traits survive and reproduce more.
What is Natural Selection
A mutation that helps bacteria survive antibiotics is an example of this.
(________ mutation)
What is a Beneficial mutation?
This type of allele masks the effect of another allele.
What is a Dominant Trait?
This mutation replaces one DNA base with another.
What is Substitution?
The cell that forms after fertilization.
What is a Zygote?
A trait that helps an organism survive or reproduce.
What is Adaptation
A bird with better camouflage survives predators more often. This is an example of this process.
What is Natural Selection?
This allele is only expressed when two copies are present.
What is a Recessive Allele?
This mutation adds extra DNA bases into a sequence.
What is Insertion?
When one cell splits into two identical cells.
What is Binary Fission?
Producing offspring that survive and reproduce.
What is Reproductive Success?
Why might a species with more genetic variation survive environmental change better?
(No need to answer in the form of a question)
Some individuals have traits that help them survive
If B represents free earlobes and b represents attached earlobes, what phenotype would Bb produce?
Free earlobes
This mutation removes part of the DNA sequence.
What is Deletion?
When a small growth forms on the parent and develops into a new organism.
What is Budding?
Differences in traits among individuals in a population.
What is Genetic Variation?
Explain why sexual reproduction increases genetic variation.
(No need to answer in the form of a question)
It combines DNA from two parents

What is Helpful, Neutral, and Harmful?
When a piece of an organism grows into a new organism.
What is Regeneration?
Why genetic variation helps species survive environmental change. (No need to answer in form of a question)
