Individuals in a population that have the traits needed to survive in the environment get to survive and reproduce. Their offspring inherit those traits. Over time, a greater percentage of the population will have those successful traits.

• Natural selection

• Selective breeding

• Artificial selection

• Mutations

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

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

What is Natural Selection?

• The process were only plants better adapted to their environment tend to survive and produce more offspring.

• The process were only humans better adapted to their environment tend to survive and produce more offspring.

• The process were individuals better adapted to their environment tend to survive and produce more offspring.

• The process were organisms better adapted to their environment tend to survive and produce more offspring.
