Sorry if I'm coming into this a little late, but I just wanted to throw in my to cents. I understand the confusion about this and I've thought about it myself quite a few times. The first Jurassic Park was released in 1993, two years before Michael Crichton wrote The Lost World and introduced the concept of a Site B and the dinosaurs being raised on another island, so there are real life reasons for this inconsistency. As for an in-universe explanation, I've come up with a theory. The only animals we actually see being bred, not taking the embryos Nedry steals into account, are the Velociraptors. In the very next scene, we're made aware of the Big One and how she killed all but two of the previously introduced pack. Now, these animals are already tremendously expensive to produce, let alone the cost of transporting them almost a hundred miles by boat from one island to another. It's possible that, in an attempt to limit the costs of replacing those animals, they simply bred the replacements on Isla Nublar. This is of course complete and total speculation and conjecture and shouldn't be taken as fact. As for why there were a large number of male animals on Isla Sorna, remember that the gaps in the gene sequences were filled with frog DNA. Why frog? I've been trying to figure that out for years. As Dr. Grant stated, some frog species can change their sex if they're present in a single sex environment for a period of time, and it's clear that someone in InGen's genetics department didn't do their research when choosing a frog to use. Since the animals on Sorna are from the same genetic stock as those on Nublar, it would make sense that there'd be a significant population of males there. Hope this helped you.
