Unit 11 Retest

What is one disadvantage of asexual reproduction for whiptail lizards that only have female individuals and no males?

• A. A new population can be established by a single individual in a relatively short period of time.

• B. All the members of a population are genetically very similar and less able to survive environmental changes.

• C. They are smaller than lizards that reproduce sexually.

• D. They are more likely to develop a variety of tail lengths.

How do hydras reproduce?

• By laying eggs

• By sexual reproduction

• By budding

• By splitting into two

What happens to a bud in the process of hydra reproduction?

• It develops into a new adult while remaining attached to the parent.

• It immediately separates and forms a new colony.

• It breaks off from the adult hydra and floats away.

• It merges back into the parent after growing.

Which of the following best describes a hydra bud?

• A hydra bud contains genetic material from its two parents.

• A hydra bud is genetically identical to the parent hydra.

• A hydra bud has different mutations than the parent hydra.

• A hydra bud is larger than the parent.

When a litter of puppies is born, the pups will exhibit certain physical characteristics that can be found in one or both of the parent dogs. These characteristics passed down from parent to offspring are considered to be:

• acquired traits

• recessive traits

• genotypes

• inherited traits

Certain species of yeast can reproduce sexually or asexually. Which answer choice best compares the offspring from sexual reproduction to the offspring of asexual reproduction?

• Offspring of sexual reproduction are larger than offspring of asexual reproduction.

• Offspring of sexual reproduction are genetically different from either parent and offspring of asexual reproduction are identical to the parent.

• Offspring of sexual reproduction have twice as much genetic material as the offspring of asexual reproduction.

• Offspring of sexual reproduction are genetically identical to each other and offspring of asexual reproduction are genetically different from each other.

Which of the following best explains the changes in genetic traits that exist among the dog species?

• Natural selection developed stronger, faster dogs.

• Genetic disorders slowly changed the dogs over time.

• Dog owners selectively bred dogs for desirable traits.

• Dogs changed their traits over time to please their owners.

Over time, sharks that have an underside that is white in color and a topside that is blue/gray in color, have survived better than sharks that were blue/gray all over. The sharks are better camouflaged from predators & prey from above and below. Which of the following best describes this scenario?

• There is actually no relationship between the shark's skin color and its ability to survive.

• Natural selection

• Selective breeding

• Survival of the strongest

Which is the type of Asexual Reproduction performed by BACTERIA?

• Meiosis

• Binary fission

• Fertilization

• Mitosis

Asexual reproduction produces offspring with DNA that is _________ the parent.

• different from

• the same as
