Spoiler:

Ulen Hibiki was Kira and Cagalli's biological dad. He and his wife Via were killed in a fire set by Rau (trying to kill Al Da La Flaga [and succeeding]) many years before the events of SEED.

Hibiki was the guy who ran the Ultimate Coordinator project. He only used Kira for his experiment, so Cagalli was totally Natural.

Kira didn't know that his "parents" were not his real parents until late in SEED.

It's not actually explained why they were separated at birth, just that it was an agreement between Lord Uzumi and Kira's "parents" (who are sister and brother-in-law to his biological mother).
