Phenotype- This is the “outward, physical manifestation” of the organism. These are the physical parts, the sum of the
atoms, molecules, macromolecules, cells, structures, metabolism, energy utilization, tissues, organs, reflexes and
behaviors; anything that is part of the observable structure, function or behavior of living organism.
Genotype- This is the “internally coded, inheritable information” carried by all living organisms. This is stored
information is used as a “blueprint” or set of instructions for building and maintaining a living creature. These
instructions are found within almost all cells (the “internal” part), they are written in a coded language (the genetic
code), and they are copied at the time of cell division or reproduction and are passed from one generation to the next
(“inheritable”). These instructions are intimately involved with all aspects of the life of a cell or an organism. They
control everything from the formation of protein macromolecules to the regulation of metabolism and synthesis.
While watching the video clips please answer the following questions.
1. Evolution changes the __________________ pool in organisms.
2. What do we mean when an organism has “high fitness” in the relationship of natural selection?
3. What mutations occur as natural selection is happening? What is affected overall?
4. Explain natural selection in relationship to bacteria and antibiotics.
5. How does diversity affect evolution? Explain by giving examples.
1. How is global warming affecting the budding of blueberries? Please explain using natural selection in the answer.
2. Mutations change your ____type. This in turn changes your _________ appearance.
3. Explain why natural selection will not work if all species had the same phenotypes.
4. Explain why some people cannot get malaria. Use the following words in your answer: genes, Mosquito and
mutations.
5. Why would it be a positive to have the altered phenotype for sickle cell anemia in Africa and why would it be a
negative for a person in Europe.
6. In natural selection, nature is deciding who lives and dies. However humans are deciding what bacteria dies and what
bacteria lives by the usage of antibiotics. Explain how humans are making bacteria stronger, and give two ways that we
can stop this trend.
