Study Notes
Sexual Reproduction
- Involves the fusion of two gametes (sperm and egg) to form a zygote
- Results in offspring with unique combinations of genetic traits
- Occurs in eukaryotes, including animals, plants, and fungi
- Increases genetic diversity due to crossing over and independent assortment of chromosomes
- Examples: humans, animals, plants, and some fungi
Binary Fission
- A type of asexual reproduction in single-celled organisms
- Involves the replication of DNA and the splitting of the cell into two identical daughter cells
- Occurs in prokaryotes, such as bacteria and archaea
- Results in genetically identical offspring
- Examples: bacteria, archaea, and some protists
Asexual Reproduction
- Includes various methods of reproduction that do not involve gametes or fertilization
- Results in offspring with identical genetic material to the parent
- Includes binary fission, budding, fragmentation, and parthenogenesis
- Examples: Hydra, starfish, corals, and some plants
Meiosis
- A type of cell division that produces gametes (sperm or egg cells)
- Involves two successive cell divisions (meiosis I and meiosis II) with no DNA replication between them
- Results in four haploid daughter cells with unique combinations of genetic traits
- Occurs in eukaryotic organisms, including animals, plants, and fungi
- Increases genetic diversity due to crossing over, independent assortment, and random fertilization
Mitosis
- A type of cell division that results in two diploid daughter cells identical to the parent cell
- Involves one round of DNA replication followed by cell division
- Occurs in somatic cells (non-reproductive cells) of eukaryotic organisms
- Results in genetically identical daughter cells
- Examples: skin cells, muscle cells, and nerve cells
