Crash Course Natural Selection

The specific alleles or version of genes that an organism inherits is its:

• Cellulartype

• Phenotype

• Chromotype

• Genotype

The actual expression of an organisms anatomy, internal functions,

or behavior in the real world is its:

• Phenotype

• Realtype

• Genotype

• Plumeytype

Natural Selection acts on traits in an organism's:

• Pommytype

• Genotype

• Phenotype

• Traitotype

Natural selection requires all of these but one.

Which is not a requirement for natural selection?

• Inheritance

• Variation

• Different Outcomes that give advantage or disadvantage

• Isolation

A forest has some very tall trees, some short trees, but mostly middle sized trees.

This is an example of

• Disruptive Selection

• Middle Selection

• Directional Selection

• Stabilizing Selection

In a forest facing a drought with not enough water, the large and medium trees die out leaving only small trees that reproduce. The whole forest's tree size is reduced.

This is an example of:

• Stabilizing Selection

• Directional Selection

• Hydro Selection

• Disruptive Selection

A population is pushed towards extremes at the same time like with beetles who fight to get a mate.

Big beetles win the fight, small beetle sneak in, medium beetles die out and can't pass on their traits.

This is called:

• Directional Selection

• Disruptive Selection

• Stabilizing Selection

• Beetlemania
