What is the two-fold cost of sexual reproduction?
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?
What is a form of asexual reproduction?
- Creation of genetically different 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.
