Reproduction Quiz

1. Which of the following best defines sexual reproduction?

• A. The fusion of two gametes to produce genetically varied offspring
• B. The production of genetically identical offspring from a single parent
• C. The division of a parent cell into two daughter cells
• D. The formation of spores by a single organism

2. What term is used to describe offspring that are genetically identical to their parent?

• A. Mutations
• B. Clones
• C. Hybrids
• D. Variants

3. A strawberry plant produces new plants through runners. Which type of reproduction is this, and what is an advantage of this method?

• A. Sexual reproduction; it produces genetic variation to help species adapt
• B. Asexual reproduction; it allows rapid colonisation of new areas without genetic variation
• C. Sexual reproduction; it requires less energy than asexual reproduction
• D. Asexual reproduction; it requires two parents to produce offspring

4. Bacteria reproduce by binary fission. Which statements about this process are correct? (i) It produces genetically identical offspring (ii) It requires two parent bacteria (iii) It is a form of asexual reproduction

• A. (i) and (ii) only
• B. (ii) and (iii) only
• C. (i) and (iii) only
• D. All three statements are correct

5. A scientist compares sexual reproduction in plants with asexual reproduction through bulbs. Which comparison correctly identifies a disadvantage of sexual reproduction and an advantage of asexual reproduction?

• A. Sexual reproduction produces clones; asexual reproduction requires less energy and produces offspring quickly
• B. Sexual reproduction produces genetic variation making adaptation difficult; asexual reproduction produces identical offspring that are already adapted to the environment
• C. Sexual reproduction requires two parents and gamete fusion; asexual reproduction can produce many offspring rapidly from a single parent
• D. Sexual reproduction is slower; asexual reproduction always produces more offspring than sexual reproduction
