Variation, Adaptation, and Mutations

This is an inherited trait that makes an individual different from other members of its species.

• Variation

• Mutation

• Punctuated Equilibrium

• Embryology

Mutations are important because they bring about

• death of the organism in which they develop

• genetic variation needed for a population to evolve

• benefits for the individual, not for the population

• Hardey-Weinberg equilibrium within a population

Why would a population with a large amount of genetic variation be more likely to survive a severe climate change in its environment?

• Individuals will only create offspring well-suited to the climate change

• The individuals would produce more offspring

• Individuals better suited to the new climate will help less-suited individuals survive

• Some individuals will posses traits better suited to the new climate and be more likely to pass them on

Which best describes the relationship between genetic variation and an organism’s ability to adapt to its environment?

• The environment causes genetic variation in a population of

  organisms, which allows them to adapt to their environment.

• Genetic variations in a population of organisms result in individuals

  with similar genetic traits and the ability to adapt to their

  environment.

• Organisms of a population have certain traits that enable them to

  adapt to changes in the environment, survive, and pass these traits

  on to offspring.

• A population of organisms with little genetic variation is better able

  to adapt to changes in their environment than organisms with a lot of

  genetic variation.
