341533
Assertion : In apomixis, plants of new genetic variations are not produced. Reason : In apomixis, reductional division takes place
1 Both Assertion and Reason are true and Reason is correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false.

Now-a-days agricultural practice is expensive to the farmers as they need to purchase hybrid seeds every year. Which of the following strategies can be employed to overcome this problem?
1 Synthetic seeds
2 Production of Apomictic seeds
3 Conventional plant breeding
4 Parthenocarpy
Explanation:
Apomixis is a type of asexual reproduction that resembles sexual reproduction. In this, seeds are produced without fertilization. Hence, all the individuals produced apomictically are gentically similar to the parent. It would drastically reduce the cost of hybrid production, so that plant breeders produce new varieties of seeds more quickly and more cheaply.

What is Apomixis?
1 Effect of low temperature on the growth of plant
2 Development of plants in darkness
3 Development of plants without the fusion of gametes
4 Plant’s inability to perceive stimulus for flowering
Explanation:
Apomixis as defined by Hans Winkler is replacement of the normal sexual reproduction by asexual reproduction, without fertilization. Apomixis is a genetically controlled reproductive process by which embryos and seeds develop in the ovule without female meiosis and egg cell fertilization.
