Class 12 Biology - Chapter 1: Reproduction in
Organisms (Short Notes)
Reproduction is the biological process by which organisms give rise to new individuals.
It ensures continuity of species generation after generation.
Types of Reproduction: Asexual and Sexual reproduction.
Asexual reproduction involves single parent and no gamete formation.
Examples of asexual reproduction: Binary fission, Budding, Fragmentation.
Sexual reproduction involves two parents and fusion of male and female gametes.
Events in sexual reproduction: Pre-fertilization, Fertilization, Post-fertilization.
Vegetative propagation is a type of asexual reproduction in plants.
Clones are genetically identical individuals produced asexually.
Offspring in sexual reproduction show variation which helps in evolution.
