Natural Selection

Sequence of DNA that determines structures of proteins

• Mutation

• Gene

• Molecule

• Protein

Complex molecules that are responsible for traits

• Protein

• Sugar

• Genes

• H2O

The way in which traits are shared in the population

• Predominant

• Resistance

• Distribution

• Heritable

Process in which traits become more/less common due to some traits making it more likely for individuals to survive and reproduce

• Natural Selection

• Mutation

• Distribution

• Adaptation

Changes in a species over generations, due to changes in the environment

• Distribution

• Mutation

• Adaptation

• Resistance

A random and permanent change to a gene

• Protein

• Gene

• Natural Selection

• Mutation

Mutations are...

• beneficial when it helps survival and reproduction

• neutral when it doesn't help or hinder survival and reproduction

• harmful when it lowers the chance for survival and reproduction

Traits become more common in a population when it increases the probability of

• survival

• mutations

• reproduction

• dying

Differences in traits are called:

• natural selection

• genetic variations

• artificial selection

• adaptations

Due to pollution, a pond becomes darker over time. Which trait variation became more common?

• light fish

• dark fish
