Questions and Answers

What is a characteristic of asexual reproduction?

  • It involves a single parent and produces genetically identical offspring. (correct)
  • It involves two parents and produces genetically identical offspring.
  • It involves two parents and produces genetically diverse offspring.
  • It involves a single parent and produces genetically diverse offspring.

    • How is genetic variation generated in sexual reproduction?

  • Through independent assortment and crossing over of chromosomes during meiosis. (correct)
  • Through mitosis and independent assortment of chromosomes.
  • Through crossing over of chromosomes during mitosis.
  • Through replication and segregation of chromosomes during meiosis.

    • In what type of environment may asexual reproduction be more advantageous than sexual reproduction?

  • In a stable environment, due to high energy expenditure and unpredictable inheritance of parental traits.
  • In an unstable environment, due to high energy expenditure and unpredictable inheritance of parental traits.
  • In a stable environment, due to low energy expenditure and predictable inheritance of parental traits. (correct)
  • In an unstable environment, due to low energy expenditure and predictable inheritance of parental traits.

    • Hydras can reproduce asexually through outgrowths from the parent
    • Plants can carry out asexual reproduction through vegetation propagation, such as budding off parts of a plant
    • In asexual reproduction, an individual inherits all its chromosomes from a single parent, making it genetically identical to the parent
    • Asexual reproduction may be advantageous in a stable environment as it requires lower energy investment and maintains successful parental characteristics
