Abstract
Summary
The radioactive isotope P32 was used as a tracer to follow the course of phosphorus combined as KH2PO4 and injected into the yolks of incubating eggs. The distribution of P32 within the various components of the eggs was determined daily throughout incubation. The distribution in ether soluble, water soluble, and trichloracetic acid pre-cipitable fractions was determined for the fluid components of the eggs from the 6th to the 14th day of incubation. From the 6th day of incubation to the day of hatching, the P32 in the embryo increased from 3% to 90%.
