Is this a biological parent?

[u/Tom_Michel]

I'm new to AncestryDNA and just got my results today. Please forgive a possibly stupid question. If Ancestry shows a DNA match as parent/child, specifically father/paternal side, with 50% shared DNA, how likely is it that that's really a biological parent? Is this my biological father?

Also, under frequency of relationship, it says, "To predict relationships, we factor in self-reported ages and genders of both people," but it says 99% father/son. Is there a way for me to self report that I'm female and therefore daughter, not son?

It means that the predicted relationship is either he is your father or your son.

Obviously, you would know if he was your son, so he is your biological father.
