Genetically modified (GM) animals have been engineered to express desired traits, which can be beneficial in various fields.
Step 1: Improved resistance to diseases.
GM animals can be engineered to have enhanced immunity, helping them resist diseases that would otherwise reduce their population or harm their utility.
Step 2: Better productivity.
GM animals can be modified for traits such as faster growth, improved reproduction rates, or better quality products (e.g., milk, meat), which helps increase agricultural efficiency.
Final Answer:
1. Improved resistance to diseases.
2. Better productivity in agriculture.
