Both a and b

Explanation:

a- Understanding the genetics of apomixis.

b- Transferring apomictic genes into hybrid varieties.

c-Both a and b is the correct option

d-Studying the occurrence of polyembryony

Apomixis is a type of asexual reproduction in plants that does not involve fertilization. This means that apomictic plants can produce offspring that are genetically identical to the parent plant. This is a very important property for the hybrid seed industry, because it allows farmers to produce hybrid crops that can be reproduced asexually.

Hybrid crops are often more productive than inbred crops, but they must be replanted each year because they do not produce viable seeds. This can be a costly and time-consuming process for farmers. Apomictic hybrid crops would be able to reproduce asexually, which would save farmers time and money.

In order to develop apomictic hybrid crops, scientists need to understand the genetics of apomixis. They need to identify the genes that control apomixis and how these genes interact. Once they understand the genetics of apomixis, they can begin to transfer apomictic genes into hybrid varieties.

This research is ongoing in many laboratories around the world. Scientists are making progress in understanding the genetics of apomixis and in transferring apomictic genes into hybrid varieties. However, there is still much work to be done.

Overall, apomictic hybrid crops have the potential to revolutionize the agricultural industry. By understanding the genetics of apomixis and by transferring apomictic genes into hybrid varieties, scientists can develop crops that are more productive, more disease-resistant, and more tolerant to environmental stresses. This could lead to increased food security and improved livelihoods for farmers around the world.
