Question

In many laboratories, active research is on to comprehend the genetics of apomixis
A. Apomixis generates genetically different individuals
B. Apomixis is the method to produce seeds without fertilization
C. Hybrid plants are directly formed by apomixis
D. Transfer of apomixis genes into hybrid varieties that shall prevent hybrid vigor loss over the years

Answer 1

Hint:
Before we proceed with the problem, it is important to know about apomixis.
When asexual reproduction replaces the typical sexual processes of cell division and fertilization, this is known as apomixis. Higher plants frequently exhibit this activity, and they are the so-called apomictic plants. Typically seen in the Rutaceae, Gramineae, and Compositae families in higher plants, apomixis is highly prevalent. Over 35 groups of plants are known to be apomictic.

Complete step by step answer:
It has been bred for many years to create hybrid seeds for a range of important crops with exceptional qualities like productivity and resistance to biotic and abiotic stress. Up until recently, a significant issue with hybrid seeds was their inability to continue producing plants with the same traits over several generations.
Natural apomixis, an asexual reproduction method that avoids meiosis and ultimately leads to the development of seeds, is an asexual reproduction that occurs in flowering plants. For several generations, apomixis can keep economically important plant genotypes in hybrid vigor.
To comprehend the biology and evolution of asexual seed production and to pinpoint the underlying genetic causes of this phenomenon, more study is required.

Option ‘D’ is correct

Note:
Synthetic apomixis has been offered as a treatment for hybrid vigor. If these hybrids are made into apomicts, there will be no character segregation in the hybrid offspring. The farmer will then be able to continue using the hybrid seeds to grow new crops without having to purchase them every year. Due to the importance of apomixis in hybrid plant varieties, numerous laboratories around the world are working on developing apomictic genes into hybrid varieties and understanding the genetics of apomixis.
