Explanation:
Detailed explanation-1: -Autonomous Specification: At this stage, each blastomere contains positional information and if they are dissociated they forms the original structure. This gives rise to the mosaic development.
Detailed explanation-2: -In contrast to the autonomous specification, conditional specification is a cell-extrinsic process that relies on cues and interactions between cells. Syncytial specification is a hybrid of the autonomous and conditional specification that occurs in insects.
