Apiculture involves the maintenance of honeybee colonies for honey, beeswax, and pollination services. Sericulture is silkworm rearing, pisciculture is fish farming, poultry is bird rearing for eggs/meat. The most common species in India is Apis indica (Indian bee) and Apis mellifera (European bee). Apiculture requires knowledge of bee biology, management of hives, and disease control.
Consider the following statements about DNA fingerprinting:
