Answer 1

Answer:

BT CROPS

Explanation:

Genetic manipulation is changing the DNA of the crops and making them more powerful. Like In Biotechnology, the DNA of a crop is changed and that crop may be become a crop which could firght with the germs or give a increase in the production. As in the BT Cotton, it has a bacteria called bacillius therengiesis which helps it to fight against the other bacterias in itself. Such how genetic manipulation is useful in agricultural practises.

Answer 2

Genetic manipulation is a process of incorporating desirable (genes) characters into crop varieties by hybridisation. Hybridisation involves crossing between genetically dissimilar plants. This is done for production of varieties with desirable characteristics like profuse branching in fodder crops, high yielding varieties in maize, wheat, etc.

Genetic manipulation is useful in developing varieties which shows:

• Genetic manipulation is useful in developing varieties which shows:Increased yield.
• Better quality.
• Shorter and early maturity period.
• Better adaptability to adverse environmental conditions.
• Desirable characteristics.
