The occurrence of the heteromorphic bivalent in some taxa and its significance is also discussed. Polyploidy has played an important role in the evolution and speciation of the taxa in the family  and  seems to be an advantage for colonising/surviving in diverse climatic and habitat conditions.  UR - https://rostaniha.areeo.ac.ir/article_105624.html L1 - https://rostaniha.areeo.ac.ir/article_105624_2931922a0d689a16b5688d980cfc4d2c.pdf ER -
