In A Nutshell Egg geometry drives development: The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller cells at the margin—a size ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires precise coordination; otherwise, the embryo could develop serious complications ...

Professor Bruce Draper uses zebrafish as a model to study development. Work from his lab in the UC Davis College of Biological Sciences shows how certain genes are linked to sex change in fish and ...
