Questions and Answers

Why do cheetahs exhibit multiple mating behavior?

  • To ensure survival in harsh environments.
  • To enhance genetic diversity within populations. (correct)
  • To signal reproductive fitness to potential mates.
  • To establish dominance within populations.

What challenges do cheetahs face due to low genetic variability?

  • Improved adaptability to new habitats.
  • Increased reproductive success.
  • Enhanced social interactions with other species.
  • Reduced health and survival rates. (correct)

How do African wild dogs maintain genetic diversity within populations?

  • By migrating to different regions regularly.
  • By engaging in solitary hunting behaviors.
  • Through selective breeding programs.
  • By employing mate selection strategies to avoid inbreeding. (correct)
