Evolution Terms part 2

Multiple Choice

An Inherited trait that increases an organism's chance of surviving and reproducing.

• variation

• vestigial structure

• adaptation

• mutation

Multiple Choice

Where the better adapted organisms survive to pass traits along to offspring.

• evolution

• natural selection

• extiction

• artificial selection

Multiple Choice

What do we call a change in a species over time?

• adaptatioin

• extinction

• environmental influences

• evolution

Multiple Choice

What contains all the genetic information needed for an organism to grow and survive?

• genome

• gene

• proteome

• haplotype

Multiple Choice

Based on these results whose blood was found in the blood stain at the crime scene?

• Bob
• Sue
• John
• Lisa

Multiple Choice

Which suspect is linked to the crime scene by this DNA analysis

• Suspect A
• Suspect C
• Suspect D
• Suspect B

Multiple Choice

A slight difference in inherited trait between individual member of the same species.

• variations

• homologous structures

• adaptations

• analogous structures

Multiple Select

Choose two examples of biological variation.

• length of neck

• color of fur

• dogs vs. cats

• pierced ears

Multiple Choice

The amount of available food can affect an organism's survival.

• True

• False

Multiple Select

Which of the following are reasons a species may go extinct? (Check all that apply.)

• loss of habitat

• new predators

• greater competition

• natural disasters

Multiple Choice

Speciation occurs when two populations of the same species become so different they can no longer interbreed.

• True

• False

Multiple Choice

Gene flow can occur through which of the following mechanisms?

• Natural selection

• Genetic mutation

• Migration of individuals between populations

• Random mating

Multiple Choice

How does gene flow affect the genetic diversity of a population?

• It decreases genetic diversity by removing alleles from a population.

• It increases genetic diversity by introducing new alleles into a population.

• It has no effect on genetic diversity.

• It decreases genetic diversity by promoting inbreeding.

Multiple Choice

Gene flow is most likely to occur between populations that are:

• Geographically isolated.

• Genetically identical.

• Physically close and interbreeding.

• Subject to different selection pressures.

Multiple Choice

Which of the following scenarios is an example of gene flow?

• A flood drastically reduces the number of a certain fish species in a lake.

• Pollen from genetically modified crops drifts to nearby organic crops.

• A mutation occurs in a lizard population, causing a new color variation.

• A predator species is introduced into an ecosystem, changing the prey species' behaviors.

Multiple Choice

What role does genetic drift play in evolution?

• It increases the fitness of individuals in a population.

• It decreases genetic variation within populations but increases genetic variation between populations.

• It ensures that advantageous traits become more common in a population.

• It has no role in evolution.

Multiple Choice

Which of the following best describes genetic drift?

• A process by which allele frequencies in a population change due to migration.

• A mechanism of evolution that occurs when an organism's traits are inherited by its offspring.

• A change in allele frequencies in a population due to chance events.

• The transfer of alleles from one population to another, leading to changes in allele frequencies.

Multiple Choice

Which of the following is NOT a factor affecting genetic drift?

• Population size

• Mutation rate

• Migration patterns

• Selection pressure

Multiple Choice

Where do adaptations come from?

• The individual organism decides to adapt

• Mutations that give an organism an advantage in its environment

• Genetic recombination during meiosis

• Both mutations and genetic recombination are sources of adaptation

Multiple Choice

What is the founder effect?

• The loss of genetic variation when a new colony is established by a very small number of individuals from a larger population.

• The process by which new species are created from existing species.

• The increase in genetic variation due to the introduction of new alleles into a population.

• The effect of natural selection on a population's genetic variation.

Multiple Choice

Genetic recombination is the production of offspring...

• with new combinations of genes

• that are completely different from the parents

• with similar genes as their parent

• that are super cute and irresistible

Multiple Select

Mutations can be (check all that apply)

• helpful

• harmful

• have no effect

Multiple Choice

Offspring sometimes inherit a gene that has a slight _, or change, from the gene the parent has.

• mutation

• adaptation

• stimulus

• response

Multiple Choice

Mutations happen

• when the environment changes

• at random

• when the animal needs to adapt

• after adaptation

Multiple Choice

Species show very little evolutionary change in the fossil record

• stasis

• artificial selection

• natural selection

• darwinism
