​

Multiple Choice

Which of the following factors influence the growth of an organism?

• Only genes

• Only environment

• Both genes and environment

• Neither genes nor environment

Open Ended

Why is reproduction considered essential for the survival of a species?

Multiple Choice

Which of the following is a key difference between sexual and asexual reproduction?

• Sexual reproduction involves two parents, while asexual reproduction involves one parent.

• Sexual reproduction creates identical offspring, while asexual reproduction creates genetic variation.

• Asexual reproduction occurs only in animals, while sexual reproduction occurs only in plants.

• Asexual reproduction requires two parents, while sexual reproduction requires one parent.

Open Ended

Explain how dominant and recessive traits are represented and inherited, using the example of eye color.

Multiple Choice

What is the expected phenotype ratio for offspring when two heterozygous parents (Bb) are crossed, according to a Punnett square?

• 3 Brown : 1 Blue

• 1 Brown : 3 Blue

• 2 Brown : 2 Blue

• 4 Brown : 0 Blue

Punnett Square - fill in

-the letters on TOP pull directly down into the two boxes below them

-the letters to the LEFT are pulled directly across to the boxes to the right-hand side

Multiple Choice

Fill in the missing square.

• Gg

• GG

Multiple Choice

Fill in the missing square.

• Bb

• bb

Genotype

Homozygous = same

Heterozygous = different

Dominant = capital letter, stronger trait

Recessive = lower case letter, weaker trait

Multiple Choice

Describe the genotype.

Homozygous or Heterozygous

Dominant or Recessive

Homo = same

Hetero = different

• = Heterozygous,

  Dominant

• = Homozygous,

  Recessive

Multiple Choice

Describe the genotype.

Homozygous or Heterozygous

Dominant or Recessive

• = Homozygous,

  Dominant,

• = Homozygous, Recessive

Percentages

• 1 BOX = 25%

• 2 BOXES = 50%

• 3 BOXES = 75%

• 4 BOXES = 100%

Multiple Choice

What percentage are Bb?

• 50%

• 25%

Multiple Choice

What percentage are Gg?

• 25%

Multiple Choice

Which of the following are applications of modern genetic technology?

• GMO crops

• Pest resistance

• All of the above

Open Ended

Describe the difference between innate and learned animal reproduction behaviors, and give an example of each.

Multiple Choice

Which of the following is NOT a strategy animals use to protect their young?

• Building nests

• Carrying young

• Photosynthesis

• Defending territory

Open Ended

Describe how both sexual and asexual reproduction benefit plants in different ways.

Multiple Select

Which of the following are methods of asexual reproduction in plants?

• Runners

• Bulbs

• Pollination

• Budding

Open Ended

Explain how the methods of seed dispersal contribute to the survival of plant species.

Multiple Choice

Which environmental factor is NOT listed as affecting plant growth in the presentation?

• Sunlight

• Wind

• Space

• Nutrients

Open Ended

How do genes and the environment together influence the growth and survival of a species?

Multiple Choice

What are the two main types of reproduction found in living organisms?

• Asexual and sexual reproduction

• Binary fission and budding

• Photosynthesis and respiration

• Mutation and adaptation

Multiple Choice

Which of the following statements best explains why reproduction is important for species survival?

• It allows traits to pass from parents to offspring, ensuring the continuation of the species.

• It helps technology improve species.

• It protects offspring from predators.

• It ensures that only the environment affects growth.
