Final answer:
The Green Revolution, known as the Second Agricultural Revolution, introduced hybrid and genetically engineered crops, marked by innovations like high-yielding varieties and genetic improvements for disease resistance.
Step-by-step explanation:
Hybrid and genetically engineered crops are characteristic of the Green Revolution, which is often referred to as the Second Agricultural Revolution. This period saw significant advancements in agricultural techniques, including the development of high-yielding varieties of wheat and rice, and the introduction of new agricultural practices. The Green Revolution was marked by an increase in crop production due to the implementation of modern technologies and methods, such as hybrid seeds and the use of genetic engineering to improve disease resistance, drought tolerance, and other important characteristics of crops.
