| Blastogenesis refers to the first 28 days of development, during which the basic body plan and domains of gene expression are established and the developmental fate of all parts of the embryo is determined. |
| Disruptions are a group of congenital disorders that result from environmental disturbances of the processes of blastogenesis and organogenesis. |
| Malformations that occur in the first twenty eight days of development are defects of blastogenesis. |
| This treatment also abolished DNA synthesis and blastogenesis which otherwise followed the peak of sterol synthesis. |
| During the first half of blastogenesis, the bilaminar disc and the basic body plan of dorsoventrality, rostrocaudal axis, and laterality are established. |
| Defects acquired during organogenesis tend to be milder than those of blastogenesis and affect single rather than multiple parts of the body and generally allow for survival of the developing organism. |
