One advantage of apomixis is that it allows for the production of offspring that are genetically identical to the parent plant, preserving desirable traits in a population. This can be useful in agriculture and horticulture for maintaining specific characteristics in crops or ornamental plants.

What is apomixis?
Apomixis is a type of asexual reproduction in which seeds are produced without fertilization. It allows for the formation of genetically identical offspring to the parent plant. This process can be advantageous for plant breeding and propagation as it maintains desirable traits.
Apomixis and nucellar embryony?
Nucellar embryony (notated Nu+) is a form of seedreproduction that occurs in certain plant species, including many citrusvarieties. During the development of seeds from plants that possess this genetic trait, the nucellar tissue which surrounds the megagametophyte can produce additional embryos (polyembryony) which are genetically identical to the parent plant. These nucellar seedlings are essentially clonesof the parent. By contrast, zygoticseedlings are sexually produced and inherit genetic materialfrom both parents. Zygotic and nucellar embryos can occur in the same seed, and a zygotic embryo can divide to produce multiple embryos.In botany, apomixis was defined by Hans Winkler as replacement of the normal sexual reproduction by asexual reproduction, without fertilization.[ 1] This definition notably does not mention meiosis. Thus "normal asexual reproduction" of plants, such as propagation from cuttings or leaves, has never been considered to be apomixis, but replacement of the seed by a plantlet, or replacement of the flower by bulbils are types of apomixis. Apomictically produced offspring are genetically identical to the parent plant.
Explain the two ways by which seeds develop without fertilization?
Seeds can develop without fertilization through apomixis, where the embryo is formed without meiosis or fertilization, producing a genetic clone of the parent plant. Another way is through parthenocarpy, where a fruit develops without fertilization, but the seeds within it are not viable.
What are the Building blocks of competitive advantage?
The building blocks of competitive advantage are cost leadership, differentiation, focus strategy, and sustainable competitive advantage. Cost leadership involves being the low-cost producer in the industry, while differentiation focuses on providing unique value to customers. The focus strategy targets a specific market segment, and sustainable competitive advantage entails creating long-term value that is difficult for competitors to replicate.
What is the definition of selective advantage and how does it contribute to the survival and evolution of species?
Selective advantage refers to a trait or characteristic that gives an organism a better chance of surviving and reproducing in its environment. This advantage allows the organism to pass on its genes to the next generation, leading to the evolution of the species over time. In essence, selective advantage plays a crucial role in the survival and adaptation of species by favoring traits that increase an organism's chances of thriving in its specific environment.

What are example of apomixis?
this is sexual reproduction of seed is called apomixis .a diploid cell in the ovule give rise to the embryo and the ovule mature into seed . which in the dendeline are disappeared by windblown fruite
What is difference between apomixis and parthinogenesis?
Generally, apomixis is reproduction in plant life without fertilization.The correct spelling is parthenogenesis and generally refers to human conception without fertilization by a man.
What is the significance of apomixis?
Apomixis is the mechanism of seed production without involving the process of meiosis and syngamy. It plays an important role in hybrid seed production. The method of producing hybrid seeds by cultivation is very expensive for farmers. Also, by sowing hybrid seeds, it is difficult to maintain hybrid characters as characters segregate during meiosis. Apomixis prevents the loss of specific characters in the hybrid. Also, it is a cost-effective method for producing seeds.
