Questions and Answers

What is the purpose of selectively breeding different dog breeds?

  • To ensure all dogs have similar traits
  • To get desired traits in specific breeds (correct)
  • To reduce genetic diversity
  • To increase genetic mutations

Why is sexual reproduction important in maintaining genetic diversity?

  • It gives rise to different physical attributes in individuals
  • It provides unique offspring by combining genes of parents (correct)
  • It ensures survival of only the fittest individuals
  • It reduces the recurrence of undesirable inherited traits

How does genetic diversity help in adapting to environmental changes?

  • By providing different physical attributes to individuals
  • By reducing the recurrence of undesirable inherited traits
  • By maintaining a pool of genes that can adapt to stress and diseases (correct)
  • By ensuring survival of only the fittest individuals
