WebSonic Hedgehog (Shh) and Patched (Ptc) were found only in the dorsal tongue epithelium [14]. Mutant analysis shows that the lack of ptc activity alters the fate of optic-lobe primordia precursors [15]. Sonic hedgehog is also involved in the induction of ventral cell type in the developing somites. ptc is a key gene in the Drosophila hedgehog ... In 1931 Arthur Fox, a chemist at DuPont, in Wilmington, Delaware, synthesized phenylthiocarbamide (PTC). Some researchers reported a bitter taste when entering his laboratory, while others, including Fox himself, experienced no such sensation. Further study of this phenomenon by L.H. Snyder in 1931 led to the conclusion that the inability to taste PTC is a recessive trait. In 1932, Albert Blakeslee conducted a large-scale study involving the inheritance … boys and girls club princeton tx
