Some of the chromosome-containing vesicles have fused into a nucleus (N). Scale bar: 1 ^m. E. The portion of the zygote nucleus probably derived from the male pronucleus has a cloud of mitochondria at one side. Scale bar: 12 ^m. F. A portion of the zygote nucleus probably derived from the female pronucleus. There are dense patches within the nucleus and the nuclear envelope is continuous. Scale bar: ^m. 41.
