Question

Can an O positive child have AB positive and B negative parents?

Answer 1

Answer:

Everyone has an ABO blood type (A, B, AB, or O) and an Rh factor (positive or negative). ... Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

Answer 2

Answer:

No.

AB+ => A & B & + allele

B- => B & B & - Allele OR B & O & - allele

O+ => O & O & + allele

hence for , O+ blood group both parents have atleast one 'O' allele . But here one parents don't have "O" allele { AB+ } .

so this combination is not possible
