Final answer:
Sexual reproduction has advantages including unique combinations of genes and variation, but it also has disadvantages such as the need for potential mates and gametes.
Step-by-step explanation:
Sexual reproduction has several advantages and disadvantages.
Advantages:
- Requires potential mates: Sexual reproduction requires individuals to find and attract potential mates. This increases genetic diversity within a population and allows for the combination of beneficial traits.
- Offspring have unique combinations of genes: Sexual reproduction leads to offspring with new combinations of genetic material. This results in increased variation, which can be advantageous in changing environments.
Disadvantages:
- Requires gametes: Sexual reproduction requires the production of specialized gametes (sperm and egg cells). This can be energetically costly for individuals.
- Offspring have variation: While variation can be an advantage, it can also introduce harmful genetic variations. This can lead to offspring with reduced fitness or susceptibility to diseases.
