Natural Selection & Heredity

Front

What is Natural Selection?

Back

Natural Selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What drives Natural Selection?

Back

Natural Selection is driven by changes in the environment and the survival of the fittest organisms.

Front

Define Selective Breeding.

Back

Selective Breeding is the process by which humans breed plants and animals for particular genetic traits.

Front

What is the role of the environment in Natural Selection?

Back

The environment determines which traits are favorable for survival, influencing which organisms reproduce.

Front

What does 'survival of the fittest' mean?

Back

'Survival of the fittest' refers to the idea that the individuals best suited to their environment are more likely to survive and reproduce.

Front

Give an example of how Natural Selection works.

Back

An example is the peppered moths in England, where dark moths survived better in polluted areas than light moths.

Front

What is the difference between Natural Selection and Artificial Selection?

Back

Natural Selection occurs naturally in the wild, while Artificial Selection is controlled by humans.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism, which can lead to new traits.

Front

How can mutations affect Natural Selection?

Back

Mutations can introduce new traits that may be beneficial, neutral, or harmful, affecting an organism's survival.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals in a population, which is essential for Natural Selection.
