Genetic Variability
The sum of all the alleles that a population of an organism can possess
What is gene pool?
The change in the allele frequency within a population is known as genetic ________.
What is genetic drift?
A mistake that occurs when DNA is incorrectly replicated (copied) or transcribed.
What is a mutation?
True or False: In genetic engineering, scientists attempt to manipulate DNA in ways other than natural processes.
What is true?
Unlike gene mutations, chromosomal mutations are rarely harmful.
What is false?
the range of genotypic differences between individuals from the same gene pool.
What is variation?
True or False: Genetic drift has been observed to create new kinds of organisms.
What is False?
What are carcinogens?
The process of determining the order of nucleotides in sections of DNA.
What is sequencing?
This process can be used to link an individual to a crime scene, identify human remains, and diagnose inherited disorders.
What is DNA fingerprinting?
The changes that occur in a population because of individuals being born, dying, or moving in/out of an area.
What is gene flow?
The measure of the health and fitness of a population (the heavier it is, the less healthy it is)
What is genetic load?
This type of mutation consists of a change to a single nucleotide in a section of DNA.
What is a point mutation?
This type of therapy uses a vector to deliver modified DNA into a cell.
What is gene therapy?
Forensics specialists analyze this during DNA fingerprinting.
What are DNA fragments?
This effect occurs when a large portion of a population dies as a result of disease or natural disaster.
What is the bottleneck effect?
A process that occurs when chromosomes switch information during meiosis.
What is crossing over?
When DNA from another source is added to an organism's DNA, the resulting DNA is known as _________ DNA (like the customized car)
What is recombinant DNA?
Two sisters are short and three are tall. This is an example of ___________.
What is variation?
The process of a bacterium passing a plasmid to another bacterium (the exchange of genes)
What is lateral gene transfer?
A change in the allele frequency of a population when a small portion moves to a new area is known as the ________ effect.
What is founder effect?
An organism having an extra or missing chromosome is a result of this (because the chromosome failed to separate during meiosis).
What is nondisjunction?
Multiple copies of a section of DNA can be produced by this process.
What is polymerase chain reaction?
These three crops are the highest genetically modified (GMO) crops.
What are corn, soy, and sugar?
