Evolution Vocab
This is the inherited changes that occur in a population over time.
What is evolution?
This is a random change to an organism’s DNA.
What is a mutation?
This is an example of a harmful mutation and what will happen over time in the population.
What is [mutation that decreases survival and reproduction], and decreasing in proportion over time, possibly leaving the population entirely?
This is the difference between a gene and an allele.
What is genes are the section of DNA used to code for a protein, while alleles are different versions of that gene?
A ______________ is a strand of DNA which determines how a particular ______________ is built.
What is gene and protein?
This is the evolution of two species in response to each other, resulting in “matching” adaptations, such as bees and flowers.
What is coevolution?
This is a type of molecule that carries the inherited information passed from parents to offspring.
DOUBLE:
What is this short for?
What is DNA?
DOUBLE
What is deoxyribonucleic acid?
This is an example of a beneficial mutation and what will happen over time in the population.
What is [mutation that improves survival and reproduction], and increasing in proportion over time?
This is how alleles are important to genetic variation.
What is providing many different versions of traits that can easily be inherited.
DNA is folded up and organized into structures called _________________ in the nucleus of a cell.
What is a chromosome?
This is the separate evolution of similar traits in unrelated species, resulting from adaptation to similar environments. One example is sugar gliders and flying squirrels.
What is convergent evolution?
What is a chromosome?
This is an example of a neutral mutation, and what happens to that mutation in a population over time.
What is [mutation that neither improves or decreases survival and reproduction], and going up and down in proportion over time?
These are the two types of flu proteins discussed in class.
What are H (hemagglutinin) and N (neuraminidase)?
This is how two related species would appear on an evolutionary tree.
What is next to each other?
This is an ancestor from which two or more different species evolved, or descended. One example is ManBearPig.
What is a common ancestor?
This is a segment of DNA that contains the instructions for building a specific protein.
What is a gene?
These four mutations cause (100 pts each):
extra toes in cats, an almost complete lack of pigmentation, more pigmentation than average, and resistance to a mosquito-killing chemical.
What are polydactylism, albinism, melanism, and DDT resistance?
This is how flu alleles may change over time.
This is how two species that convergently evolved would look on an evolutionary tree.
This is when two species continually evolve traits to either hunt and kill the other, or escape predation by the other.
This is a specific version or form of a gene, such as one that causes a person's eyes to be brown or one that causes fingernails to be flexible.
What is an allele?
These are the two causes of mutations.
What is naturally occurring during cell division or caused by UV radiation?
This is one challenge of creating vaccines.
What is the quick rate that viruses evolve, the many alleles they may possibly inherit, or the fact that may strains of the flu circulate in the population at the same time?
This is where a common ancestor would be found on an evolutionary tree.
