Battle and coexistence of genres for survival

The study of genres is one of the important subjects in the field of literary critique and theories, which gained importance again in contemporary literature following the upswing of critique field. The advancement of discussions related to literary genres also faced challenges. The genres came in to existence for different reasons. For example they sometimes form sub-genres of the same type inside themselves or form them independently; they may also live inside the dominant genre as a recessive genre, associate with other (genres) or form kinship relationships. Coming in to existence, Sub -genres also pass the same way. By mixing genres and sub-genres,they sometimes generate genres and small genres in different manners . The small genres also put the same effort for their survival. In such a situation, some subgenres and small genres fade and sometimes they may revive (so-called resurrect) in other situations. These relationships and the progress of genres from the beginning to the end-which can be called struggle for survival in genres-can, solve problems like the ingenuousness of genres, the impossibility of including subgenres under a specific genre and the mixture of genres, subgenres and small genres.
