Effects of Cadmium and Zinc on the Gamete Viability, Fertilization, and Embryonic Development of Tripneustes gratilla (Linnaeus)

Figure 2

Representative images showing T. gratilla different gamete morphologies (400x). This network of thread-like blue material (white arrows) strongly indicates that there is a result of leaching DNA materials when a cell undergoes necrosis due to the attachment of Giemsa stain onto sites where adenine and thymine are rich.
