Asexual & sexual

• What is a key advantage of asexual reproduction?

  Only one parent is needed
• Why is asexual reproduction considered quick?

  It allows rapid colonization by one organism
• What is a disadvantage of asexual reproduction regarding offspring?

  All offspring are clones with no genetic variation
• How does a disease affect a population reproducing asexually?

  If one organism is affected, all are susceptible
• What is a consequence of low genetic variation in asexual reproduction?

  Less chance of adapting to new conditions
• What is a key advantage of sexual reproduction?

  It introduces genetic variation in offspring
• How does genetic variation benefit a population during disease outbreaks?

  Some individuals may be more resilient to disease
• What is a disadvantage of sexual reproduction in terms of time and energy?

  It takes more time and energy to find a mate
• What are the two types of gametes involved in sexual reproduction?

  Sperm and egg
• How many chromosomes do gametes have?

  Each gamete has 23 chromosomes
• What happens when two gametes fuse?

  They create a cell with 46 chromosomes
• How are gametes produced?

  Through meiosis
• What is a characteristic of asexual reproduction in plants?

  It involves only one parent and no gametes
• What process do eukaryotic organisms use for asexual reproduction?

  Mitosis
• How do prokaryotic organisms reproduce asexually?

  By binary fission
• What are the main differences between asexual and sexual reproduction?

  • Asexual reproduction:
  • One parent
  • No gametes
  • Offspring are clones
  • Quick process
  • Sexual reproduction:
  • Two parents
  • Involves gametes
  • Offspring are genetically varied
  • Takes more time and energy
