Reproduction Quiz

A human skin cell contains 46 chromosomes. How many chromosomes are present in a human sperm cell?

• 12

• 92

• 46

• 23

The gamete that contains genes contributed only by the mother is:

• an egg

• the sperm

• a zygote

• diploid

If an organism’s diploid number is 12, what is the haploid number?

• 12

• 6

• 24

• 3

Which characteristic is present in offspring produced by sexual reproduction, but is missing in offspring produced by asexual reproduction?

• An independent assortment of parent chromosomes

• an identical copy of parent chromosomes

• Only half the number of parent chromosomes

• Twice the number of parent chromosomes

Which process produces the most variation within a species?

• cloning

• sexual reproduction

• mitosis

• asexual reproduction

How are sexual reproduction and asexual reproduction different?

• Sexual reproduction produces offspring identical to the parents, but asexual reproduction produces offspring with trains from both parents.

• Sexual reproduction only occurs in multicellular organisms, but asexual reproduction only occurs in unicellular organisms.

• Asexual reproduction only occurs in multicellular organisms, but sexual reproduction only occurs in unicellular organisms.

• Asexual reproduction produces offspring identical to the parents, but sexual reproduction produces offspring with traits from both parents.

A student used a microscope to observe a single-celled organism. As he watched, it looked as if the organism split into two cells. He made drawings, shown below, of the organism over a short period of time.

Which process did the student record in his drawings?

• sexual reproduction

• asexual reproduction

• gamete formation

• selective breeding

Gametes must be haploid cells because:

• two gametes will unite during sexual reproduction to create a diploid cell

• the gametes’ chromosomes will be replicated prior to cell division

• fertilization results with a haploid zygote

• gametes are small and can hold only the haploid number of chromosomes

The picture shows a hydra budding. Budding would be an example of which of the following

• Fertilization

• Sexual Reproduction

• Asexual Reproduction

• Creating genetically diverse offspring

Guppies are a type of fish that come in a variety of colors. Based on this information which of the following is a true statement

• The guppies reproduce sexually and have uniform offspring

• The guppies reproduce sexually and have diverse offspring

• The guppies reproduce asexually and have uniform offspring

• The guppies reproduce asexually and have diverse offspring.
