MECHANISMS OF EVOLUTION JEDI TRAINING

Individuals choose a mate based on their appearance or location

• natural selection

• genetic drift

• gene flow

• mutation

• nonrandom mating

Answer explanation

A mate is being CHOSEN. It is NOT RANDOM.

New gene is added through a change in DNA

• natural selection

• genetic drift

• gene flow

• mutation

• nonrandom mating

Answer explanation

A NEW gene. A NEW change in the DNA. That is a mutation

New individuals immigrate into a population

• natural selection

• genetic drift

• gene flow

• mutation

• nonrandom mating

Answer explanation

Gene flow deals with movement. One individual going from one population to another. This individual bring its DNA (genes).

Organisms better adapted, or better suited are more likely to survive and reproduce in their environment

• natural selection

• genetic drift

• gene flow

• mutation

• nonrandom mating

Answer explanation

ADAPTATION!!!!

SURVIVAL and REPRODUCTION!!!!!

That is natural selection

Chance or random event reduces population

• natural selection

• genetic drift

• gene flow

• mutation

• nonrandom mating

Answer explanation

Two clues

1. Random event

2. Reduction of population

This is GENETIC DRIFT

Reduces genetic diversity by reducing population

• natural selection

• genetic drift

• gene flow

• mutation

• nonrandom mating

Answer explanation

Two clues

1. Reduction of genetic diversity

2. Reduction of population

This is GENETIC DRIFT

A male hawk arrives to a new forest and mates with the resident female.

• natural selection

• genetic drift

• gene flow

• mutation

• nonrandom mating

Answer explanation

Gene flow deals with movement. One individual going from one population to another. This individual bring its DNA (genes).

• natural selection

• genetic drift

• gene flow

• mutation

• nonrandom mating

Answer explanation

A mate is being CHOSEN. It is NOT RANDOM.
