OH, that reminds me. The theory I mentioned? First….where do you think the starters are born? ANY generation.
The theory I've read, states there's like, breeding ranches. Where they have couples constantly pumping out eggs. The labs are just distributors.
Also? Because they need constant egg sources, the girls are often kept, to pump out even more eggs.
BUT, they do give out some of the girls.
That if you're on said ranch, yes, the gender ratio IS 50/50. It's just the males that are more likely to be given away to trainers.
