Somite formation is thought to be regulated by an unknownoscillator mechanism that causes the cells of the presomiticmesoderm to activate and then repress the transcription ofspeciÞc genes in a cycli.

Plant embryogenesis is the process that produces a plant embryo from a fertilized ovule by asymmetric cell division and the differentiation of undifferentiated cells into tissues and organs. . You are preparing to select embryo(s) for a patient having a fresh, day 5 embryo transfer. Your patient is aged 37 years and has had one previous fresh, day 5 embryo transfer with a single top-quality blastocyst. The previous transfer resulted in a negative pregnancy test.  .

The different stages in the development of individual organs are known as ontogeny and the study of the history of development of species or race is called its phylogeny. .
