NATURAL SELECTION

Front

What is the primary source of genetic variation in a population?

Back

Mutations are the primary source of genetic variation, introducing new traits into a population.

Front

If a new trait DOES NOT provide an advantage to an organism, what may happen to the organism?

Back

The organism may die and its DNA is not passed on to the next generation.

Front

What is the term for inherited trait differences in a population?

Back

Variations are the inherited trait differences found within a population.

Front

What is a characteristic of an organism that is determined by genetics?

Back

A Trait is a characteristic of an organism that is influenced by its genetic makeup.

Front

What is the process by which organisms better adapted to their environment tend to survive and produce more offspring?

Back

Natural Selection is the process where organisms with advantageous traits survive and reproduce.

Front

What is the term for the movement of genes between populations?

Back

Gene Flow refers to the transfer of genetic material between populations.

Front

What is the difference between phenotype and genotype?

Back

Phenotype is the observable characteristics of an organism, while genotype is the genetic makeup.

Front

What is genetic drift?

Back

Genetic Drift is a change in the frequency of an existing gene variant in a population due to random sampling.

Front

What is the role of environmental factors in natural selection?

Back

Environmental factors influence which traits are advantageous, affecting survival and reproduction.

Front

What is an example of a trait that may provide a survival advantage?

Back

Camouflage is a trait that can help an organism avoid predators.
