Problem:

There are numerous species of animals who use parthenogenesis, but to my knowledge the reproduction is clonal. That is, the offspring are identical to the mother.

Question: Are there any documented cases where a female goes through meiosis one to produce varied cells that are now diploid and these cells do not go through meiosis two, but rather develop in to a diploid organism?

It would seem an effective reproductive strategy in that it generates genetic variation without a mate (at least more-so than strict asexual reproduction).

Is my logic flawed in some way? Please give your suggestions.
