Modes of Reproduction (Asexual vs Sexual) MCQs

Q1. How is the number of accumulated variations in a population related to the number of individuals in it?

• A.A larger population can accumulate more variations over time
• B.More individuals always means fewer variations
• C.The number of individuals has no effect at all on variations
• D.Variations only occur in populations of exactly one individual

Answer: A. A larger population can accumulate more variations over time

Q2. What are the advantages of sexual reproduction over asexual reproduction?

• A.Sexual reproduction allows for greater variation and genetic diversity.
• B.Sexual reproduction is faster than asexual reproduction.
• C.Sexual reproduction is slower than asexual reproduction.
• D.Sexual reproduction has no advantages over asexual reproduction.

Answer: A. Sexual reproduction allows for greater variation and genetic diversity.

Q3. Which is an advantage of sexual reproduction over asexual?

• A.it needs only one parent
• B.it is faster
• C.it produces variation useful for evolution
• D.it makes exact clones

Answer: C. it produces variation useful for evolution

What is the textbook's take? An ionic bond forms when a metal donates electrons to a non-metal: e.g. Na -> Na+ + e-, Cl + e- -> Cl-, and Na+ + Cl- -> NaCl; the resulting solid is held by strong electrostatic attraction => this fixes the property asked in the stem; hence the answer = it produces variation useful for evolution. Does that line up with one of the options? Yes - Correct. And the rest? option A) 'it needs only one parent' is incorrect: Sexual needs two parents; option B) 'it is faster' is wrong because Asexual is faster; sexual gives variation. Pick: C) it produces variation useful for evolution.
