Every time two dragons are bred, there are odds that the combo will be X dragon. Those odds are set, but the chances are random. It's like flipping coins-you may be likely to get an even split of heads/tails if you flip enough times, but it's completely possible to flip a coin 100 times and land on heads every time.

It really is random.
