Parthenogenesis When development of organism takes place without fertilization, the process is called as parthenogenesis. Parthenogenesis is of two types viz. 1.       Natural 2.       Artificial Natural parthenogenesis: ·          Eggs that develop without fertilization naturally, the process is called as natural parthenogenesis. ·          It is commonly seen in Aphids, Phyllopods and Rotifers at sometimes of the years not always ·          Whereas in case of bees and wasps males are always produced from unfertilized egg. Thus, males are always haploid and females are diploid because females are produced from fertilized egg. ·          In some species such as Tenthredinidae, reproduction is alays parthenogenetically and males of this species are not known. ...
