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

  • 9. When is being genetically identical to the parent an advantage for organisms?
A) When many offspring are needed in a short amount of time.
B) When the environment is just like the one the parent lived in successfully.
C) When the enviroment is changing and fast reproduction is needed.
D) When no mates can be found.
