- Crop Biotechnology: Biotechnology is used in the agricultural field to improve yield and variety.
- Hybrid Seeds: Genes of two different crops are recombined to form hybrids of various crops. This is especially useful for fruits.
- Genetically Modified Crops: Crops developed with desired characters by integrating foreign genes with their genome are called genetically modified crops. High-yielding varieties with resistance to diseases, alkalinity, weeds, and other stresses like cold and drought.
- Animal Husbandry: Two main methods, artificial insemination and embryo transfer, are used in animal husbandry. It helps to improve both the quantity and quality of animal products. Ex. Milk, meat, wool, etc. Similarly, animals with more strength have been developed for hard work.
