The given information is not enough to tell us which of the t nits-blood group A or O � is dominant In blood heredi, bood type A is always dominant and blood type O is always recessive. Here, father's Blood group can be 1AIA (homozygous) or IAi theterozygous) genotypically, where that of mother is if. For daughter to be born with blood group O, she must receive i type gene one each from father and mother. For this father must have heterozygous IAi blood group and mother must have homozygous blood group ii.
The information is not enough to decide which blood group is dominant.
But universally , blood group A is dominant whereas blood group O is recessive.
case 1: For an A group father it may be homozygous (AA) or heterozygous(A0) as pairs.So as A is dominant and an O group mother, the O group is recessive, then the daughter may have either group O Or A.
If A from father crosses with O of mother then blood group of daughter =A(dominant)
case 2:But if O from father crosses with O of mother then blood group of Daughter=) (as recessive) blood group expressed in homozygous condition.
