Natural Selection

Front

What are mutations?

Back

Mutations are changes in the DNA sequence of an organism.

Front

What is speciation?

Back

Speciation is the evolution of one or more species from a common ancestor, leading to the formation of a new species.

Front

Why are advantageous traits more likely to be passed onto offspring?

Back

Advantageous traits are more likely to be passed onto offspring because they increase the chances of survival and reproduction.

Front

What is fitness in the context of natural selection?

Back

Fitness refers to the ability of an organism to survive and reproduce in a specific environment.

Front

What does evolution mean?

Back

Evolution refers to the change over time in the genetic composition of a population.

Front

What is natural selection?

Back

Natural selection is the process by which organisms with advantageous traits are more likely to survive and reproduce.

Front

What is genetic equilibrium?

Back

Genetic equilibrium is a state in which the genetic composition of a population remains constant over time.

Front

What is adaptation?

Back

Adaptation is a trait that increases an organism's fitness in a specific environment.

Front

What is the role of variation in natural selection?

Back

Variation provides the raw material for natural selection, allowing some individuals to have traits that are better suited for survival.

Front

How does environmental change affect natural selection?

Back

Environmental change can alter which traits are advantageous, leading to shifts in the population's genetic makeup.
