Is ganondorf links father in Zelda orcarina of time?

Gannondorf is King of the Gerudo thieves while Link is of Hylian descent.

The game doesn't reveal too much of links origins, other than that he was born from a Hylian mother and that his mother died delivering him to the Kokiri Forest to the Great Deku Tree during the Hyrulean Civil War.

while the scenario is highly unlikely, there isn't any concrete evidence to say absolutely no, but seeing as Link has blond hair, blue eyes and white skin, while Gannondorf has red hair, brown eyes and darker skin, Link possesses no physical genes with Gannondorf. usually at least some form of trait develops from both parents of a child.

seeing as there is no evidence of Gannondorf being Links father, and plenty of evidence to the contrary, my guess would be no.
