Apogamy is:
Updated On: Jul 27, 2022
- reproduction of virus
- failure of fusion of gametes
- development of bacteria
- loss of function of reproduction
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Apogamy was first reported by Farlow $(1874)$. It can be defined as the development of a sporophyte directly from the gametophyte without the intervention of sex organs and gametes. The sporophyte formed usually have the same chromosome number as the gametophyte (i.e. the haploid number for the species). It is common and wide spread phenomenon in ferns.
e.g., Dryopteris, Pteris, Pellaea, Adiantum etc.

- Asexual reproduction involves a single parent to produce offspring without the formation of gametes. It occurs by the following ways: Fission, Budding, Fragmentation, Spore formation and Regeneration. In one of the methods like regeneration, Planaria A is cut horizontally into three pieces – L, M and N and Planaria B is cut vertically into two equal halves – O and P.
(a) Which of the cut pieces of the two Planaria could regenerate to form a complete organism?
(b) Give an example of another organism which follows the same mode of reproduction as Planaria.

Concepts Used:
Asexual Reproduction
The mode of reproduction in which a new offspring is produced by a single parent is known as asexual reproduction. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.
Features of Asexual Reproduction:
- Only single parents are involved.
- The fertilization or gamete formation cannot take place.
- This process of reproduction occurs in a very short time.
- The organisms multiply and grow rapidly.
- In this offspring produced is genetically similar.
