  • 2. In binary fission how does the DNA of the daughter cells compare to the DNA of the parent cell?
A) It is only half of the amount of DNA found in the parent.
B) It is identical.
C) It is a mix of the parent's DNA.
D) It has some similarities and some differences.
  • 3. How many parents are required for asexual reproduction?
A) two
B) six
C) one
D) four
  • 4. In order to survive and reproduce organisms need to have what type of traits?
A) Traits that make them the smartest.
B) Traits that make the the most attractive.
C) Traits favorable for survival.
D) Traits like the parents.
  • 5. How can asexually reproducing organisms gain some genetic diversity?
A) crossing over
B) mutations
C) mitosis
D) meiosis
  • 6. What process creates gametes for sexual reproduction?
A) mitosis
B) independent assortment
C) meiosis
D) crossing over
  • 7. Why does the process the creates gametes also create genetic diversity?
A) Prophase and anaphase mix up the DNA.
B) Mitosis I and II mix up the DNA.
C) Two parents contribute DNA.
D) Crossing over and independent assortment mix up the DNA from the mother and father.
