Did the goat people (zonai) and the Hylians, you know…

If Rauru and Sonia are Zelda’s ancestors, I have questions about the logistics. Sonia, sure, I can buy it. But Rauru is a whole ass goat man. Because the Zonai are gone, we can’t really ask any of them about their reproductive capabilities. Is Zelda’s family the only cross-species descendent from the early days of Hyrule? Or is there a little bit of Zonai in all the people of Hyrule? I need a Tears of the Kingdom sicko to explain it to me. The tables have turned. I am asking this question instead of answering it.
