Introduction
Page Under Development
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. In humans, this cell then undergoes a series of mitotic cell divisions, still enclosed within the zona pellucida, during the first few days of development to form 2 blastomeres then a solid cell mass called the morula.
