REVIEW

An advantage of asexual reproduction is that it does not require fertilization. What advantage do the offspring of sexual reproduction most likely have as a result of fertilization?

• The DNA variation in offspring may allow survival in a changing environment.
• The DNA of the offspring is the same as the parent.
• The offspring must use energy to find a mate.

Vertebrate animals produce offspring by sexual reproduction. Which is an advantage of this type of reproduction?

• Time and energy is used to find a mate in the population.
• There is increased genetic diversity within the population.
• The offspring grows faster than one that is produced asexually.

Potatoes can reproduce asexually. Each sprout on a parent potato can grow into a new potato plant. How does the genetic material in the sprout compare to the parent potato?

• The sprout has a random genetic assortment.
• The parent potato has twice the genetic material of the sprout.
• Both the sprout and the parent potato have the same genetic identity.

Organisms that reproduce asexually generally have offspring that are

• genetically varied.
• genetically identical.

Bacteria are organisms that reproduce asexually. What would the traits inherited by a newly produced bacterium be like?

• different from the traits of the single parent
• the same traits as the single parent
• different from the traits of two parents

In animals, female traits are passed down to offspring from

• sperm.
• seeds.
• eggs.

When an egg and sperm form an embryo, the offspring that is formed will have genetic traits that are

• inherited from only one parent.
• passed on from two parents.

A plant that has traits identical to the parent plant provides evidence that the plant

• resulted from sexual reproduction.
• resulted from asexual reproduction.

Why does sexual reproduction result in more genetic diversity than asexual reproduction?

• Traits from two parents are combined.
• Offspring grow in different environments.

A plant that has traits identical to the parent plant provides evidence that the plant

• resulted from sexual reproduction.
• resulted from asexual reproduction.
