Why is DNA important?

it serves as the blueprint for traits of all living things

it is very small and very complicated

because we eat it every day for energy

A short length of DNA that codes for a protein.

A long length of DNA that codes for a chromosome

A short length of DNA that codes for a chromosome

What does a Punnett Square help you do?

Determine the ratio of phenotypes

Determine the ratio of genotypes

Predict possible traits the offspring will have

What is the phenotype of the offspring? (A-Brown hair; a-blond hair)

75 % Brown Hair and 25% Blond Hair

50 % Brown Hair and 50% Blond Hair

25 % Brown Hair and 75% Blond Hair

0% Brown Hair and 100% Blond Hair

Which best describes how we get our traits?

Genes control protein production, and proteins determine our traits.

Proteins control chromosome production, and chromosomes determine our traits.

Genes control chromosome production, and chromosomes determine traits.

Proteins control gene production, and genes determine our traits.

What results if a gene sequence (code) is changed.

A change to the protein would occur.

A negative mutation would occur.

A genetic mutation will most immediately affect...

The number of chromosomes within each cell of the body.

The ability of the organism to survive.

The overall health of the organism.

Which mutation would be beneficial?

It depends on which is best suited to survive in the environment.

Which mutation would be neutral?

The mutation has no impact on the health of the population.

The mutation appears to increase in the population over time.

Individuals that have the mutation appear to reproduce at a greater rate.

The mutation is high in organisms with short life spans.

LEVEL 4 Survival of a species group would be more greatly impacted by a mutation that occurs during mitosis. (true or false)

False, because the purpose of mitosis is replacing cells for an individual so the whole species group would not be affected.

True, because the purpose of mitosis is replacing cells for an individual so the whole species group would not be affected.

True, because the purpose of mitosis is to create sex cells for an individual so all the offspring of that species group would be affected.

False, because the purpose of mitosis is to create sex cells for an individual so all the offspring of that species group would be affected.

LEVEL 4 Survival of a species group would be more greatly impacted by a mutation that occurs during meiosis. (true or false)

True, because the purpose of meiosis is to create sex cells for an individual so all the offspring of that species group would be affected.

True, because the purpose of meiosis is replacing cells for an individual so the whole species group would not be affected.

False, because the purpose of meiosis is replacing cells for an individual so the whole species group would not be affected.

False, because the purpose of meiosis is to create sex cells for an individual so all the offspring of that species group would be affected.

LEVEL 4 Which type of mutation would have the most impact and why?

A chromosomal mutation because it could change 100s to 1000s of traits.

A gene mutation because it could change 100s to 1000s of traits.

Both types of mutations would affect 100s to 1000s of traits.

The coronavirus mutation because it could affect 100s to 1000s of people.
