What is Parthenogenesis?. Is it similar to Ants or Honey bee that male and female both can be produced from Parthenogenesis or only exact replica forms like in case of Moina?.

How do mOina reproduces Parthenogenetically?.Do they also release Male Moina? Is mode of reproduction changes in unfavorable conditions than from where the male Moina has come from??.

How do we differentiate Male and female Moina?.
During the parthenogenetic cycle, females produce diploid eggs that develop directly into females. The same female may produce diploid asexual eggs that develop into males. Male production is under environmental control. Furthermore, the same female may produce haploid eggs that require fertilization by males. These eggs are then enclosed in a protective shell (ephippia) and need to undergo diapauses before female offspring will hatch from them.
