Study Notes
Types of Reproduction
- Two main types of reproduction: sexual reproduction and asexual reproduction.
Genetic Recombination
- Genetic recombination occurs during sexual reproduction, enhancing genetic diversity and adaptation by mixing parental genes.
Disadvantage of Sexual Reproduction
- The main disadvantage of sexual reproduction is its energy and time requirement, involving processes like finding a mate and developing offspring.
Advantage of Asexual Reproduction
- The primary advantage of asexual reproduction is the fast reproduction rate, allowing organisms to produce numerous offspring quickly without the need for a mate.
Costs Associated with Sexual Reproduction
- Four key costs of sexual reproduction include:
- Resource investment in finding and courting a mate.
- Risks of disease transmission between mating individuals.
- Lower reproductive rates, since producing a few offspring may take time compared to asexual methods.
- Potential for genetic mismatches leading to less fit offspring due to the combination of genes from two parents.
