I think you're misunderstanding the nature of parthenogenesis; it's quite different from cloning. Here, let Auntie Wikipedia explain it to you:
"Parthenogenesis is distinct from artificial animal cloning, a process where the new organism is necessarily genetically identical to the cell donor. In cloning, the nucleus of a diploid cell from a donor organism is inserted into an enucleated egg cell and the cell is then stimulated to undergo continued mitosis, resulting in an organism that is genetically identical to the donor. Parthenogenesis is different, in that it originates from the genetic material contained within an egg cell. Egg cells may be produced via meiosis or mitosis oogenesis.[4] If by mitosis, the egg that undergoes parthenogenesis can be either haploid or diploid, leading to a number of possible outcomes in terms of the genetic fingerprint of the parthenogen (one created via parthenogenesis). Whether the parthenogen is haploid or diploid, because meiosis was involved in forming the gamete that subsequently underwent parthenogenesis, incidence of crossing over would effectively create a new genetic fingerprint; this would be of particular importance in the case of a haploid parthenogen, in which crossing over would drastically alter its single chromosome genotype. Because there are so many variables in parthenogenesis, there is little that can be said for sure unless the specific methods of the particular parthenogenetic tendencies of an organism are known."
