What is common between vegetative reproduction and apomixis?
A. Both are applicable to only dicot plants.
B. Both bypass the flowering plants.
C. Both occur round the year.
D. Both produce progeny identical to the parent.
Solution
In vegetative reproduction plants produced genetically identical offsprings that have all the characteristics of a parent. Apomixis produces clonal progeny with a maternal genotype.
Complete answer:
In asexual reproduction only one parent involves. Depending upon the conditions in which organism is reproducing, asexual reproduction have various modes. Asexual reproduction can be classified as multiple fission, plasmotomy, budding, sporulation, binary fission, fragmentation, and vegetative propagation.
There are several plants of which sections such as the root, stem, and leaves grow into new plants under suitable conditions. In fact, as in most species, plants may use this mode of reproduction. This vegetative propagation property is used for the growing of many species, such as sugar cane, roses or grapes, in techniques such as grafting or grafting for agricultural purposes. Plants reproduced by vegetative propagation can bear fruits and flowers earlier than those produced by seeds. These methods also make it possible to disperse plants such as orange, banana, jasmine, and rose which have lost their seed production ability. Another benefit of vegetative propagation is that all plants produced are genetically identical to the parent plant to have all its characteristics.
Apomixis is a method for the development of seed without fertilisation. It is a kind of asexual reproduction that mimics sexual reproduction, where the female gametophyte or ovule in the flower grows directly into an embryo that skips meiosis and syngamy. As a result, apomixis produces a clonal progeny with a maternal genotype.
Thus, the correct answer is option āDā i.e., Both produce progeny identical to the parent.
Note: The offspring formed by vegetative reproduction and apomixis are similar to their parents, as the process of fusion of gametes does not take place, so there is no recombination of characters. The offspring are formed by mitosis.
