Asexual vs. Sexual Reproduction

Question 1

What creates genetic variation in the offspring of sexually reproducing organisms?

Answer 1

genetic recombination (crossing-over) during meiosis I

Question 2

What type of cell division is used to produce gametes for sexually reproducing species?

Answer 2

Meiosis

Question 3

Animals have many different possible coat colors. What does this show?

Answer 3

Variation in sexually reproducing species.

Question 4

Name the advantages of asexual reproduction.

Answer 4

Maintain desirable characteristics found in parent.
Only requires one parent.
Increased rate of reproduction.
Usually greater amounts of offspring.

Question 5

Name the disadvantages of asexual reproduction.

Answer 5

All offspring are genetically identical to parent and each other.
Low genetic diversity.
Species cannot readily adapt to a changing environment.

Question 6

Name the advantages of sexual reproduction.

Answer 6

Offspring are genetically different to parent and each other.
High genetic diversity
Species can readily adapt to a changing environment.

Question 7

Name the disadvantages of sexual reproduction.

Answer 7

Requires 2 parents.
Energy expensive for organism.
Rate of reproduction is longer.

Question 8

What type of cell division is used by asexually reproducing species?

Answer 8

Mitosis

Question 9

Geranium plants grown from a piece cut off a parent plant will be genetically ______ to parent plant.

Answer 9

Identical

Question 10

Mutations can only be passed to offspring in sexually reproducing species in what kind of cell?

Answer 10

Gametes.

Question 11

Plants that undergo sexual reproduction produce ______.

Answer 11

Seeds.
