Question 1

Which of the following is a major advantage of asexual reproduction in plants and animals?

Accepted Answer

It is energy efficient and allows for rapid population growth.

Question 2

Which process is responsible for the production of gametes in both males and females?

Accepted Answer

Meiosis

Question 3

A population of aphids reproduces asexually during the summer and sexually during the winter. What is the most likely evolutionary advantage of this reproductive strategy?

Accepted Answer

Asexual reproduction allows rapid population increase in favorable conditions, while sexual reproduction increases genetic diversity in challenging conditions.

Question 4

Which of the following best describes the genetic outcome of asexual reproduction?

Accepted Answer

Offspring are genetically identical to the parent.

Question 5

In sexual reproduction, what is the primary function of fertilization?

Accepted Answer

To restore the diploid number of chromosomes in the zygote.

Question 6

Which of the following is NOT a method of asexual reproduction?

Accepted Answer

Fertilization

Question 7

During spermatogenesis, how many functional sperm cells are produced from one diploid spermatogonium?

Accepted Answer

Four

Question 8

Which equation correctly represents the chromosome number change during gametogenesis in humans?

Accepted Answer

$$2n \xrightarrow{meiosis} n$$

Question 9

Which of the following statements about oogenesis is correct?

Accepted Answer

Oogenesis produces one functional ovum and three polar bodies from each primary oocyte.

Question 10

A farmer grows a crop of potatoes using only tubers from a single parent plant. What is a major risk associated with this method of asexual reproduction?

Accepted Answer

The entire crop is susceptible to disease due to lack of genetic variation.

Question 11

Which of the following is a disadvantage of sexual reproduction compared to asexual reproduction?

Accepted Answer

It requires more time and energy investment.

Question 12

Which reproductive strategy is most likely to be found in aquatic species and why?

Accepted Answer

External fertilization, because water facilitates the meeting of gametes.

Question 13

Which of the following best explains why sexual reproduction leads to greater genetic diversity than asexual reproduction?

Accepted Answer

Sexual reproduction combines genetic material from two parents through meiosis and fertilization.

Question 14

Which of the following is an example of parthenogenesis?

Accepted Answer

A whiptail lizard producing offspring without fertilization.

Question 15

If a mutation occurs during meiosis in gametogenesis, which of the following is a possible consequence?

Accepted Answer

The mutation may be passed to offspring if the affected gamete is involved in fertilization.

Question 16

Which of the following equations represents the fusion of gametes during fertilization?

Accepted Answer

$$n + n \rightarrow 2n$$

Question 17

Which reproductive process is most likely to result in offspring that are clones of the parent?

Accepted Answer

Asexual reproduction

Question 18

Which of the following is a real-world example of regeneration as a form of asexual reproduction?

Accepted Answer

A starfish regrowing a lost arm.

Question 19

Which of the following statements about gametogenesis is correct?

Accepted Answer

Gametogenesis occurs in the gonads and involves meiosis.

Question 20

Which of the following is a key difference between spermatogenesis and oogenesis?

Accepted Answer

Spermatogenesis produces four functional sperm per primary spermatocyte, while oogenesis produces one functional ovum per primary oocyte.
