| Outline of Final Research Achievements |
In this study I investigated neonate production potential of Moina macrocopa females hatched from parthenogenetic eggs and resting eggs. There were no varieties between the fecundities of the females made by parthenogenesis within same generation and also across generations. However, the fecundities of the females hatched from resting eggs which were obtained from a clone population had significant variety within same generation. Moreover, the average value and the standard diviation of neonate production potential of resting egg-progenies derived from larger-reproductive population was same as resting egg-progenies derived from less-reproductive population. It was suggested that the phenotype is maintained across parthenogenetic reproduction, and polymorphism, which is not genetic polymorphysm, is generated at resting egg production.
Unexpected result changed investigate plans. I tried to carry out epigenetic analysis, but cannot completed in this investigation period.
