Specific sequences of DNA that determine the relationship of structures during development; often expressed in a gradient across the embryo.

Cytoplasmic Segregation Routes

Cellular mechanisms involved in the distribution of cytoplasmic components between daughter cells during cell division.

Embryonic Signposts

Critical markers or events in the development of an embryo that guide the process of embryogenesis.

Induction Genes

Genes that are activated (or induced) by specific environmental conditions or stimuli, leading to the production of functional proteins as a response.
