• What are the two ways organisms can reproduce?

  Sexual and asexual reproduction
• What is sexual reproduction?

  Fusion of two gametes like sperm and egg
• What is asexual reproduction?

  Mitosis forms an identical clone of the parent
• What are the advantages of asexual reproduction?

  • Only one parent needed
  • Very quick process
  • Rapid colonization of new areas
• How quickly can a single bacterium colonize a new area?

  Within just a couple of days
• What is a downside of asexual reproduction?

  No genetic variation among offspring
• How does lack of genetic variation affect a population?

  Increases susceptibility to diseases
• What are the advantages of sexual reproduction?

  • Leads to genetic variation
  • Reduces risk of population wipeout
  • Allows for adaptation and evolution
• Why is genetic variation important in a population?

  It helps resist diseases and adapt to changes
• What is evolution?

  Process by which species change over time
• What is the main disadvantage of sexual reproduction?

  It takes more time and energy
• Why do some birds have colorful feathers?

  To impress their potential mates
• What is required for animals to reproduce sexually?

  Finding and impressing potential mates
• What are the key differences between sexual and asexual reproduction?

  • Sexual: Requires two gametes, genetic variation
  • Asexual: One parent, identical clones
