Study Notes
Differences Between Sexual and Asexual Reproduction
- Sexual reproduction involves the combination of genetic material from two parents, resulting in unique offspring.
- Asexual reproduction produces offspring genetically identical to the single parent, with no genetic diversity.
Asexual Reproduction Methods
- Occurs in prokaryotes (like bacteria) and some eukaryotes.
- Binary Fission: Parent cell divides to form two identical daughter cells; common in single-celled organisms.
- Fragmentation: Parent breaks into fragments, with each capable of developing into a new organism (e.g., starfish can regenerate from a single arm).
- Budding: A new organism develops from a bud on the parent, detaching when fully formed (e.g., yeast).
Asexual Reproduction Advantages
- Enables rapid population growth, especially in favorable conditions; bacteria can exponentially multiply.
- Allows organisms to occupy ecological niches quickly, often outcompeting slower-reproducing species.
Limitations in Asexual Reproduction
- Bacterial reproduction is constrained by limited resources, predation, and waste accumulation.
- Asexual reproduction lacks genetic variation, which can be a disadvantage in changing environments.
Sexual Reproduction Process
- Involves two parents producing gametes (reproductive cells) that unite during fertilization.
- Gametes are haploid, containing half the organism's total chromosomes; fertilization creates a diploid zygote.
- Meiosis is responsible for producing haploid gametes, ensuring genetic variation through recombination.
Key Definitions
- Gametes: Reproductive cells for sexual reproduction.
- Zygote: The fertilized cell that develops into a new organism and is diploid.
