What is the difference between asexual and sexual reproduction?
What is the difference between asexual and sexual reproduction?
Asexual reproduction involves a single parent and produces genetically identical offspring, while sexual reproduction involves two parents combining gametes to produce genetically unique offspring.

Study Notes
Animal Reproduction
- Animals reproduce through asexual or sexual methods, with some capable of both.
- Sexual reproduction is complex, involves haploid gametes, and produces genetically unique offspring.
- Hermaphrodites or monoecious organisms produce both male and female gametes, often avoiding self-fertilization.
Asexual Reproduction
- Asexual reproduction involves a single parent, producing genetically identical clones.
- Key characteristics include no fertilization, rapid multiplication, and identical genetic makeup of offspring.
- Common types of asexual reproduction:
- Regeneration: Replacement of lost or damaged body parts through tissue production.
- Budding: Formation of a new individual from an outgrowth on the parent, seen in organisms like hydras.
- Parthenogenesis: Development from an unfertilized egg through mitosis, common in species such as aphids and wasps.
Sexual Reproductive Strategies
- Some species can change sex during their lifecycle (e.g., clownfish exhibit protandry by transforming from male to female).
- Allows adaptation to environmental or social changes.
Animal Nutrition
- Essential nutrition for animals includes twelve essential elements and thirteen vitamins important for physiological functions.
- Examples of essential elements:
- Calcium is crucial for the formation of bones and teeth.
- Chlorine is involved in forming hydrochloric acid (HCl) in the stomach.
- Copper plays a role in synthesizing melanin and hemoglobin.
