Two plump blastomeres sit side by side inside the zona pellucida in this two-cell embryo model, split by the first cleavage furrow. Each cell carries a clearly raised round nucleus, and the softly pitted surfaces contrast with the smooth outer shell that holds them together. The shapes are simple and easy to read from across a room. A clean teaching piece for a biology or embryology classroom, a fertility clinic desk or a science shelf, showing the very first step of development after fertilization.
