Nature has a way of causing organisms that inherit advantageous traits to survive and reproduce more successfully than the ones that don't. This process is known as...

• natural selection

• genetic variation

• adaptation

A trait that helps an organism survive and reproduce is a(n)

• Natural Selection

• Phenotype

• Adaptation

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.

 The diagram shows a population of ladybugs that changed over 15 years. What is the  likely explanation for this change?

• Wings are an advantageous (good) trait.

• Black spots are an advantageous (good) trait.

• Red coloring is an advantageous (good) trait.
