Roux's own mosaic framework predicts that reserve idioplasm must be progressively consumed during determination, making its persistence through later divisions logically inconsistent with the theory's core commitments.

mosaic framework(as Roux's theoretical model of development)
An old scientific theory suggesting that an embryo develops like a mosaic tile pattern, where each cell is predetermined from the start to become a specific part of the organism.
reserve idioplasm(Roux's auxiliary hypothesis to account for regenerative capacity in simpler organisms without abandoning mosaic determination theory)
A backup store of determinative material retained within each cell's nucleus, providing the capacity to reconstitute a whole organism if needed
