Introduction
The first diploid cell that forms following fertilization by fusion of the haploid oocyte (egg) and spermatozoa (sperm) resulting in the combination of their separate genomes. The first image shows the cell with the 2 pronuclei still present before fusion enclosed within the zona pellucida.
