Natural Selection
Environment.
This change occurred in the environment of Peppered Moths
Trees became darker/covered in soot and smoke
This word refers to a change in an organism's DNA that did not come from their parent(s).
Mutation
This type of genetic technology can cure or treat some diseases
Gene therapy
This form of reproduction requires mutation in order for natural selection to occur.
Asexual reproduction
What two variations were present in populations of Rock Pocket Mice?
Black fur and brown fur
This word refers to differences between animals of the same species
Variation
This genetic technology has been used to create many different breeds of dogs
Artificial selection
A beetle's environment changes from a dark to a light color. After this environmental change, what 2 things will light colored beetles be able to do which will cause natural selection to occur?
Survive and reproduce
Squirrels in many cities are changing to become a grey/black color more often than a brown one. This helps them blend in with the city environment humans have built. What type of technology/concept is this an example of?
Natural selection
This word describes a trait that helps an organism survive in its environment
Adaptation
This genetic technology is used to remove and replace a section of DNA, giving an organism new traits
CRISPR
List both ways that genetic variation can occur in a population.
Mutation and sexual reproduction
A scientist decides she wants to bring back the wooly mammoth from extinction. She extracts some preserved mammoth DNA, and uses a living elephant to develop an organism with this same DNA. What genetic technology/process did this scientist carry out?
Cloning
This term describes a process that can cause genetic variation, without changes to the DNA received from either parent.
Sexual Reproduction
This genetic technology sometimes requires the nucleus of an egg cell to be replaced with another organism's genetic code, and implanted in a surrogate animal before being born.
Cloning
This term describes natural selection that results in the creation of a new species
Speciation
A farmer wants to grow crops that produce more food per plant. He identifies a section of DNA that causes larger crop yields, and uses genetic technology to insert this section of DNA into his plants. He then only plants seeds from plants that grow the most food. Which two technologies did this farmer use?
CRISPR and artificial selection
This term describes something like a virus used in gene therapy to carry a DNA sequence to its target in the body.
A vector
This protein is an important part of the CRISPR system, and has the specific job of cutting out a section of DNA.
CAS9 (or just CAS)
