The plotline there, as far as I remember, was that bullfrog DNA meant that some female dinosaurs could actually morph to become male and reproduce with the females (this is something that happens in some fish, amphibians, and even reptiles, where sex is not genetically determined).
Correct, and they had a designed lysine deficiency that was supposed to make them reliant on human-given dietary supplements to live. By consuming lysine-rich foods they were able to live without humans and some gradually changed sex to become male, leading to viable reproductive groups on the island.
Somewhat. In both cases, females were able to self-reproduce. In the film, females switched to male to fertilize. In the condors case, eggs developed without fertilization from males who were available.
Yes, it is exactly this plot line for how the dinosaurs were able to reproduce. All the animals were selected to be female to prevent natural reproduction.
