Meiosis Quiz (2nd)

Which process can occur in both mitosis and meiosis?

• fertilization

• independent assortment

• gene mutation

• crossing over

How are mitosis and meiosis similar?

• both require DNA replication

• both produce gametes

• both involved crossing over

Gametes produced by an organism contain a combination of genes from that organism. In

every gamete, this combination is —

• the same because it is created from the same DNA

• the same because chromosomes are copied prior to meiosis

• different due to DNA replication prior to mitosis

• different due to independent assortment during meiosis

Crossing-over between nonsister chromatids during meiosis is significant in heredity. This

process most likely leads to an increase in which of the following?

• The expression of dominant traits

• Number of gametes

• The occurrence of polyploidy

• Genetic variation

Human body cells each have 46 chromosomes in their nuclei. Meiosis is necessary in order to

ensure that each gamete produced in the human body has —

• 23 chromosomes

• 46 chromosomes

• 92 chromosomes

Sexual reproduction in animals depends on the production of gametes. Which of these

processes produces gametes in animals?

• Mitosis

• Fertilization

• Meiosis

• Binary fission

Why is meiosis important for sexual reproduction?

• It allows the zygote formed from fertilization to have triple the chromosome number of the organism.

• It allows gametes to have twice the original number of chromosomes of the organism.

• It allows gametes to have half the original number of chromosomes of the organism.

• It allows the zygote formed from fertilization to have half the original number of chromosomes of the organism.

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

• an identical copy of parent chromosomes

• twice the number of parent chromosomes

• only half the number of parent chromosomes

• an independent assortment of parent chromosomes

How are sexual reproduction and asexual reproduction different?

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

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