My blood type is o negative. my dad is o negative. i don't know my mom's blood type, but based on mine and my dad's type, what could hers be?

She could not be AB. She could have been A, or B, or O. she could not have been homozygous Rh positive but could have been heterozygous Rh positive. As heterozygous Rh positive she would have been positive.
