Questions and Answers

What is the two-fold cost of sexual reproduction?

  • Only 50% of organisms reproduce and organisms only pass on 50% of their genes (correct)
  • It creates genetically similar or identical copies of organisms
  • It involves the cloning of an organism
  • It requires the sexual interaction of two specialized reproductive cells

What is a form of asexual reproduction?

  • Creation of genetically different copies of organisms
  • Sexual interaction of two specialized reproductive cells
  • Cloning of an organism (correct)
  • Passing on 100% of genes to offspring

What are gametes?

  • Organisms created by asexual reproduction
  • Offspring organisms derived from parental genes
  • Specialized reproductive cells containing half the number of chromosomes (correct)
  • Genetically identical copies of organisms

Study Notes

Reproduction Costs

  • The two-fold cost of sexual reproduction includes the cost of producing gametes and the cost of finding a mate.

Asexual Reproduction

  • Binary fission is a form of asexual reproduction.

Gametes

  • Gametes are haploid cells that fuse to form a diploid zygote during sexual reproduction.

Comparison of Reproduction Methods

  • The key difference between asexual and sexual reproduction is that asexual reproduction produces genetically identical offspring, whereas sexual reproduction produces genetically diverse offspring.

Sexual Reproduction

  • In sexual reproduction, offspring organisms are produced when gametes (sperm and egg cells) fuse to form a zygote, which then develops into a new individual.
