Summary
Morphogenetic effects of evans blue and of Zn++ inLytechinus variegatus embryos are described. Viable unhatched maximally-animalized embryos were induced with 4.2×10−5 M evans blue and with 4–8×10−4 M ZnCl2. Hatching inhibition was reversed only with ZnCl2 suggesting that Zn++ is the preferred animalizing agent in this sea urchin species.
