• beaks

• feet

• sizes

• language (songs)

Genetic fitness means that an organism's ability to do what is high?

• lift weights really well

• reproduce effectively

• attract other members of their species

• survive environmental disasters

Microevolution happens in

• species

• individuals

• populations

• households

T5. What does the image represent?

• Founder effect
• Bottleneck effect
• Mutation
• Natural Selection

What type of selection is depicted in the picture where one phenotype is favored?

• stabilizing

• directional

• disruptive

If finches with large beaks and finches with small beaks increase in a population while finches with average sized beaks decreases, which pattern of natural selection has occurred?

• Directional selection
• Disruptive selection 
• Stabilizing selection

Natural selection requires ______________ to happen in a population.

• hundreds of years

• variation

• low genetic fitness

• high genetic fitness

What type of selection is shown in the image?

• Stabilising

• Directional

• Disruptive

What type of selection is shown in the image?

• Stabilising

• Directional

• Disruptive

What is genetic drift?

• the changes in allele frequencies (genes) ,in a population, happening due to random events/circumstances.

• It is an example of primary succession

• Genetic drift are different organisms in a population due to inherited traits from their parents

• It is part of symbiotic relationships such as mutualism, commensalism, parasitism
