H. Woldington, Buchanan Professor of Animal Genetics at the Uni- versity of Edinburgh yesterday. "All organisms pass on traits to their offspring and these off- spring must differentiate," said the foremost specialist in the fields of embryology and genetics who i TheDELRIORE . for the BEST pizza in TOWN also SPAGHETTI * RAVIOLI * STEAKS CHOPS CHICKEN CALL us to order REAL CORNISH PASTIES for picnics.

Regions Become Distinct Regionalization occurs when these regions become distinct enough to manifest traits. Finally, morphogenesis results in the actual appearance of bodily shape and structures. Prof. Waddington expanded on the relation of the genes to the cytoplasm. The cytoplasm may limit the potentialities of the gene but the gene, however, determines the cytoplasm. This interaction illustrates the cyclical nature of gene and cytoplasm behavior. The exact transmission of in-. . .. . formation from the nucleus to the cytoplasm is of major concern to the geneticists, while the return of certain information from the cytoplasm back to the nucleus holds the attention of the em-, bryoligists. Differentiation into the final product is a complex process that is best handled by specialists from many fields. Radioactive Tracers Used Prof. Waddington concluded his lecture with a discussion of em- bryonic induction, the process whereby one partof the embryo may stiniulaite another part to form an organ or structure. He noted that radioactive tracers are used to trace the substances re- sponsible for induction. The biochemistry of induction differs between an embryo and an adult.
