Studies the early stages of the development of the axolotl, an aquatic salamander, with emphasis upon genetically determined characteristics. Mates two wild-type, dark axolotls, each heterozygous for white and albino mutations. Uses time-lapse photography to show cleavage to the blastula stage, gastrulation, and neurulation. Observes rotation and elongation of the embryo, followed by identification of the gills, somites, and eyes. Records as the embryo breaks free of the vitelline membrane. Shows the well-developed gills, heart, and eyes in a later state. Concludes by showing the dark, golden albino, white, and white albino larvae.
