Question

Desired improved variety of economically useful crops are raised by

• A. Mutation
• B. Biofertilizer
• C. Hybridization
• D. Natural selection

Answer 1

The correct option is C

Hybridization

The correct option is C.

The explanation for the Correct option:

1. Hybridization is the process of creating new types by mating two or more genetically engineered plants together.
2. Hybridization entails making a cross between the two parents in order to produce children with the desired characteristics.
3. A single cross between two plants is referred to as a single cross, while several crosses between more than two parents are referred to as multiple crosses.
4. For instance, wheat variety development.

The explanation for the Incorrect options:

Option A:

Mutation breeding is a fast approach to introducing unexpected alterations to a plant's genome.

Option B:

1. A biofertilizer is a substance made up of active or dormant microbial cells.
2. Biofertilizers enhance host plant nutrients by applying them to their seeds, the plant surface, or the soil, and colonizing the plant's rhizosphere.

Option D:

1. Natural selection is the process through which populations of living creatures adapt and adjust.
2. Individuals in a population are fundamentally variable, which means they are all different in some ways.

Final answer: A desired improved variety of economically useful crops are raised by Hybridization.
