Is it possible for the sex of an animal to be determined after the zygote is formed? Can you give me an example so that it is easier for me to understand? Thanks!

ever seen the movie finding nemo? those type of fish do it on a regular basis..in their case they change sex depending on the ratio of males to females
but there are other organisms that change sex during their lives randomly as well

Clown fish do that. There is one female clown fish per school. If something were to happen to her, one of the males would undergo a transformation that would turn them into a female. Not 100% the same as Jurassic Park, but it is a real life example. So, if Finding Nemo were fact based then Nemo's dad would have turned into his mom.

Some fish can change back and forth.
With others, such as alligators, the sex is determined by the incubation temperature of the egg -- but the alligator does not change again after being hatched.

The sheepshead fish will turn from female to male at the death or disappearence of the local male. Once a male is reintroduced the transformation of the female is suspended.

There are some species that are hermaphrodites, or change sex, or something. I'm not exactly sure how it works, but here's an article on these animals:

Among clownfish, when two clownfish decide to mate, the larger one becomes a female!
But no, not in most species. especially just poof! like that.

You might start by looking up the frog referenced in the movie.

The things in Jurassic park cannot be done. So what you are asking is stupid.

Among some creatures (amphibians and a few others) yes.
