5 Fingers of Evolution/Limiting Factors | Baamboozle - Baamboozle

Any movement of individuals, and/or the genetic material they carry, from one population to another is known as:

Pointer finger - gene flow

Name the five mechanisms (the 5 fingers) of evolution WITHOUT looking at your study guide/notes

Genetic drift (shrinking population), nonrandom mating, mutations, gene flow, natural selection

This occurs when the probability that two individuals in a population will mate is not the same for all possible pairs of individuals

Ring finger - nonrandom mating

Individuals or organisms moving OUT of a population is known as:

Emmigration (gene flow)

As the prey population _________________, the predator population increases.

Increases

True/False: Because of limiting factors, the number of organisms in a population is often well below carrying capacity.

True

The maximum number of individuals of a species that an ecosystem can support is defined as

Carrying capacity

Because of ______________________, each ecosystem has a limited capacity for growth connected to its carrying capacity

Limiting Factors

When a small sample of a population begin a new population in a location separated from the original population it is known as what type of genetic drift?

Founders effect

When migrating individuals breed with a new population and contribute their genes to the gene pool of the local population it is known as:

Pointer finger - gene flow

A random change in an organism's genetic makeup, which will influence the populations gene pool is known as:

Middle finger - mutations

A parasite is introduced into the population that feeds on and eventually kills all humans with blood EXCEPT O+ blood. What type of genetic drift is described here?

Bottleneck effect

Will smaller populations result in MORE or LESS spread of parasites and disease?

Less

Which limiting factor is missing from the following list: Predators, Available habitat, Weather, Diseases and parasites, competition

Fire

This limiting factor is seen more often when a population is large and in close contact with one another

Diseases and Parasites

Storms, Drought, Flooding, Extreme heat/cold, are examples of what type of limiting factor?

Weather

What finger of evolution is defined as when individuals in a population are not equal, some are better adapted and more likely to survive and reproduce

Thumb - Natural Selection

Organisms moving IN to a population is defined as:

Immigration

An event that causes a population to suddenly decline to a very low number is defined as:

Genetic Drift - Bottleneck Effect

A change in the frequency of an allele within a population over time is defined as:

Genetic Drift - pinky finger

True/False: Mutations are not a true source of genetic variation with a population because we have knowledge of how, when, and why they will occur

False

An abiotic or biotic factor that restricts the number of individuals in a population is defined as a:

Limiting Factor

An organism using courtship behavior in order to find a preferable mate would be categorized under what finger of evolution?

Ring finger - nonrandom mating

A predictable change in the community over time is defined as:

Ecological Sucession

In what limiting factor do humans play the largest role in influencing?

Available Habitat

This limiting factor is kept at a delicate balance between two different species and two different populations
