Study Notes
Sexual Reproduction
- The defining feature of sexual reproduction is the production of offspring with unique combinations of traits, resulting from the fusion of gametes (sperm and egg cells) from two parents.
Exceptions to Sexual Reproduction
- Sexual reproduction does not occur in prokaryotic organisms, such as bacteria and archaea.
Analogy in Bacteria
- Conjugation, a process in bacteria where genetic material is exchanged between two cells, is analogous to sexual reproduction.
Role of Meiosis
- Meiosis is a critical process in sexual reproduction, as it involves the reduction of diploid (double set) chromosomes to haploid (single set) gametes, ensuring genetic diversity in offspring.
Organisms Exhibiting Sexual Reproduction
- Most eukaryotic organisms, including plants, animals, fungi, and protists, exhibit sexual reproduction as the most common life cycle.
