The two benefits of physical reproduction are variation and disease resistance. The costs are time consumption and favorable genes might not be passed to the offspring.
What are the costs and benefits of physical reproduction?
Benefits:
- Variation: Genetic variation means a process that says “survival of the fittest” which survivors pass on their traits to their offspring, which allows the species to evolve according to the needs of the environment.
- Disease resistance: A greater level of genetic diversity allows for higher levels of natural disease resistance within a species.
Costs:
- Time consumption: It takes time and energy to locate a suitable mate with the preferable traits that are needed to produce a healthy offspring.
- Favorable genes could not be passed on to the offspring: A combination of the two parents genes are passed to the offspring so it is possible for favorable genes to not be passed to the offspring.
