What results from asexual reproduction?

• offspring that are genetically identical to the parent

• offspring that are genetically different from each other

• offspring that are genetically different from the parent

• offspring that are genetically identical to similar species

How are meiosis and mitosis similar?

• Both are processes used in asexual reproduction

• Both are processes that produce daughter cells with the same number of chromosomes as the parent cells

• Both are processes used to replace dead skin cells

• Both are processes that form new cells necessary for the survival of either an organism or a species

The picture below shows a ciliate, a single-celled protist, undergoing a process called binary fission. Binary fission is an asexual process. Which statement is correct about binary fission?

• It is a mitotic process

• It is a meiotic process

• It will ultimately result in four daughter cells that each hold half of the DNA of the parent cell

• It will ultimately result in two cells that are genetically different and able to pass on different traits

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

• It introduces genetic variation, which increases the survival rate of a species when environmental changes occur

• It is a more reliable form of reproduction, as it requires the search for a mate that is the best match to form offspring

• It requires internal fertilization, which is easier and requires less energy than asexual reproduction

• It has slower reproductive rate, decreasing the amount of mutations that occur in the offspring

Which of the following statements is correct?

• Somatic cells are produced through mitosis, and germ cells are produced through meiosis

• Somatic cells are produced through meiosis, and germ cells are produced through mitosis

• Both somatic and germ cells are produced through only mitosis

• Both somatic and germ cells are produced through only meiosis

The picture below shows the cellular processes that four rat cells, each holding 92 chromosomes, underwent. Use the picture to answer any questions that follow.

• Cell W

• Cell X

• Cell Y

• Cell Z

In mitosis, replication occurs before the cell divides. What is the purpose of replication?

• to provide each new cell with an exact duplicate of the original DNA

• to transfer half of the traits of the parent cell to each new daughter cell

• to remove defective base pairs from the DNA before the parent cell divides

• to divide the parent cell's genes equally between the two new daughter cells

Which of these events happens during sexual reproduction only?

• DNA is copied in the parent organism before cell division

• A parent organism splits in half and makes two offspring with identical DNA

• The DNA from two parents combines to create an offspring with unique DNA

• Offspring are produced with DNA that is identical to either one parent or other
