Reproduction Basics: Trivia Exam Quiz!

1.

The New Mexico whip-tail lizard can reproduce both sexually and asexually. The most reliable way to determine that a group of offspring of whip-tail lizards was produced through asexual reproduction would be to look for which of the following characteristics?

A.

Physical appearance of the offspring
B.

Habitat location of the offspring
C.

Behavior patterns of the offspring
D.

Genetic uniformity of the offspring

Correct Answer
D. Genetic uniformity of the offspring

Explanation
You would only know that the offspring were reproduced asexually IF the genes for the offspring are all the same (uniform) as the parents.

2.

The offspring of an organism produced through asexual reproduction is always:

A.

Created by vegetative propagation
B.

Genetically identical to its parents
C.

Made of cells with a cell wall
D.

Different from its siblings

Correct Answer
B. Genetically identical to its parents

Explanation
Because there are not two parents in asexual reproduction, there are no genes to mix. The offspring get 100% of the genes from one parent.

3.

If two organisms reproduce sexually, then their offspring will have a genetic make-up that is:

A.

Identical to only one parent
B.

Identical to all of its siblings
C.

A unique or different combination of traits
D.

The recessive traits from each parent

Correct Answer
C. A unique or different combination of traits

Explanation
Sexual Reproduction produces offspring with a mix of genes from both parents, half from the mother and half from the father.

4.

Prokaryotes like bacteria cells reproduce asexually by:

A.

Binary fission
B.

Spore formation
C.

Budding
D.

Vegetative propagation

Correct Answer
A. Binary fission

Explanation
Prokaryotes like bacteria cells reproduce asexually through binary fission. In this process, the parent cell divides into two identical daughter cells. The genetic material is replicated, and then the cell elongates and divides into two, each containing a copy of the genetic material. This results in two identical offspring cells. Spore formation is a method of reproduction used by some eukaryotes, not prokaryotes. Budding is a form of asexual reproduction seen in yeast and some other eukaryotes. Vegetative propagation is a method used by plants to reproduce asexually, but it is not applicable to prokaryotes.

5.

All of the offspring of an organism have the same genetic material, which is identical to the parent organism. From this, we can conclude that this organism

A.

Makes its own food
B.

Reproduces sexually
C.

Lives in a marine habitat
D.

Reproduces asexually

Correct Answer
D. Reproduces asexually

Explanation
Asexually produced offspring have the same (identical) genes as the parents.

6.

Provided is a table of organisms and some data on their characteristics. Based on the information in the table, which organism is likely to produce offspring with the greatest genetic diversity?

A.

Black mold
B.

Bell tree dahlia
C.

Spruce
D.

Hydra

Correct Answer
C. Spruce

Explanation
According to the table, Spruce are produced sexually.

7.

Which of the following is an organism that usually produces asexually?

A.

Humans
B.

Cats
C.

Bacteria
D.

Birds

Correct Answer
C. Bacteria

Explanation
Single celled organisms like bacteria do not have males and females.

Rate this question:

8.

Which is not a type of asexual reproduction?

A.

Budding
B.

Regeneration
C.

Fertilization
D.

Binary fission

Correct Answer
C. Fertilization

Explanation
Fertilization requires male sperm and female eggs.

9.

What is the main advantage of sexual reproduction?

A.

Offspring are identical
B.

The diversity in the offspring will increase
C.

Parents and offspring have identical genes
D.

Offspring are uniform

Correct Answer
B. The diversity in the offspring will increase

Explanation
Because the offspring have a mix of genes from both parents AND you never know what the mix is going to be, offspring from sexual reproduction are genetically diverse. All the offspring are different.
