🔹 Asexual Reproduction – Detailed Explanation

🔸 What Is It?

Asexual reproduction is a form of reproduction where a single organism produces offspring without the involvement of gametes (sperm and egg).

The offspring are genetically identical to the parent (clones).

🔸 Types of Asexual Reproduction

Type How It Happens Example Organisms

Binary Fission The cell splits into two equal parts Bacteria, Amoeba

Budding A small part grows out of the parent, breaks off Hydra, Yeast

Fragmentation Body breaks into parts, each part grows into a new organism Starfish, Planaria

Spore Formation Parent produces spores that grow into new organisms Fungi, Moss

Vegetative Propagation New plants grow from roots, stems, or leaves Potato, Ginger, Strawberry

Parthenogenesis Female produces offspring without fertilization Some insects, lizards, fish

🔸 Advantages of Asexual Reproduction

✅ Fast and efficient

✅ No need for a mate

✅ Good for stable environments

✅ All offspring can reproduce

🔸 Disadvantages

❌ No genetic variation

❌ All offspring are equally affected by disease or environmental change

❌ No evolution or adaptation through reproduction
