Berry

The berry is the egg, used in constructions like ‘singleberry', a child whose cradelmate did not 'take'. The default is a 'doubleberry' ie where both eggs produce a child each. In the Pushpa-Pia Process, two eggs each from the two partners are harvested, and the nucleus is extracted from one each. The code from the stripped berries is inserted into the whole egg, and various manipulations carried out to turn off genetic imprinting. This produces a valid embryo, and these are then reimplanted by the sentinel into the people whose eggs they were.
