Quiz 1 for the MCPS biology unit on inheritance

Questions and Answers

1.

If the diploid number of chromosomes in an organism is 28, then the haploid number is ____.
- A.
  
  Also 28.
- B.
  
  56.
- C.
  
  14.
Correct Answer
C. 14.

Explanation
The haploid number is 1/2 of the diploid number. Therefore, 1/2 of 28 is 14.

Rate this question:
2.

Which of the following increases the variation of traits found in gametes?
- A.
  
  Telophase II
- B.
  
  Crossing over
- C.
  
  Asexual reproduction
Correct Answer
B. Crossing over

Explanation
Variation of traits is increased when the tail of one of a homologous pair of chromosomes trades places with the tail of the other member of the pair.

Rate this question:
3.

In sexual reproduction, two gametes combine to form a __________.
- A.
  
  Daughter cell
- B.
  
  Chromatid
- C.
  
  Zygote
Correct Answer
C. Zygote

Explanation
gamete + gamete = zygote

Rate this question:
4.

A sperm cell of a moth has 112 chromosomes. How many chromosomes are in the moth's wing cells?
- A.
  
  66
- B.
  
  112
- C.
  
  224
- D.
  
  448
Correct Answer
C. 224

Explanation
112 would be the haploid number. There fore the wing cell ( a body cell) would have a diploid number, or double that, i.e. 224.

Rate this question:
5.

Reproductive cells are produced during ______________.
- A.
  
  Mitosis
- B.
  
  Meiosis
- C.
  
  Fertilization
- D.
  
  Budding
Correct Answer
B. Meiosis

Explanation
Reproducitve cells is another term for egg and sperm. Egg and sperm are produced in meiosis.

Rate this question:
6.

Which of these is produced as a result of fertilization?
- A.
  
  A zygote with twice the number of chromosomes as a gamete
- B.
  
  An egg with half the number of chromosomes as a zygote
- C.
  
  A gamete with twice the number of chromosomes as a zygote
- D.
  
  A zygote with half the number of chromosomes as a gamete
Correct Answer
A. A zygote with twice the number of chromosomes as a gamete

Explanation
Fertilization results in a zygote. The zygote has a diploid number of chromosomes.

7.

Corals are marine animals that often live in tropical seas. Many types of corals have unicellular algae living in their tissues. The algae provide up to 98 percent of the corals' food. The corals provide protection and inorganic nutrients for the algae. Some coral cells undergo meiosis. Which of these would not occur during meiosis?
- A.
  
  Formation of a zygote
- B.
  
  Chromosomes crossing-over
- C.
  
  Production of gametes
- D.
  
  Reduction in number of chromosomes
Correct Answer
A. Formation of a zygote

Explanation
Meiosis is meiosis--in corals or any other living organisms. Therefore this is a question about meiosis in general, NOT about corals. A zygote is produced during fertilization, not meiosis, so the answer is A.

Rate this question:
8.

Sea stars are genetically different from each other and from their parents. These genetic differences are the result of ____.
- A.
  
  Mitosis
- B.
  
  Cloning
- C.
  
  Sexual reproduction
- D.
  
  Asexual reproduction
Correct Answer
C. Sexual reproduction

Explanation
Mitosis, cloning, and asexual reproduction all produce identical copies.

Rate this question:
9.

Which of these does not occur during meiosis?
- A.
  
  Production of identical gametes
- B.
  
  Production of new gene combinations
- C.
  
  Crossing-over of homologous chromosomes
- D.
  
  Reduction of chromosome number by one-half
Correct Answer
A. Production of identical gametes

Explanation
During meiosis, the process of crossing-over of homologous chromosomes occurs, which leads to the production of new gene combinations. Additionally, meiosis involves the reduction of chromosome number by one-half through the separation of homologous chromosomes. However, meiosis does not result in the production of identical gametes, as it involves the shuffling and recombination of genetic material, leading to genetic diversity among the gametes produced.

Rate this question:
10.

Sexual reproduction needs meiosis for the production of haploid gametes.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Meiosis is a type of cell division that produces haploid cells, which are necessary for sexual reproduction. During meiosis, the number of chromosomes is halved, resulting in the formation of gametes (sperm and eggs) that contain half the genetic material of the parent cells. These haploid gametes can then fuse during fertilization to form a diploid zygote, which develops into a new organism. Therefore, sexual reproduction does indeed require meiosis for the production of haploid gametes, making the statement true.
