Yes - blood type O or B are the only possibilities. Each parent donates one allele to the child. The parent with blood type O must donate an O. The parent with blood type be will donate either a B or an O - they can only donate an O if they are heterozygous, BO.
Male or female doesn't make a difference in blood type. A and B are dominant over O, and positive is dominant over negative.
no
I am O positive and my husband is A negative, and our son is A negative, for some reason children mostly take their fathers blood group, but not always, other possible blood groups the baby could be would be either yours or your husbands blood type.
The child will be O- or A-.
both is not a good term . but both parents are included in determining that
yes sibblings wih
B positive.
my mothers blood was o negative and because the child gets the fathers blood; which wasn't o negative my mother had to reveive shots

Just because the babys blood and the fathers blood is different, it doesnt mean that there is a possibility that he ain't the father. For example, my fathers blood is different from my sisters and including but he still my father. I hope that answered your question. You are A dominant, but you have the O+ recessive gene. To rephrase what the others have said- if the mother is A plus, she would be AA or AO bloodtype. The father is something with an O as well, if the baby has an O. Father could be BO< AO< OO etc. (or he could have negative blood, and still have a positive blood child from this union)
Yes, it is possible for siblings to have different biological fathers, known as heteropaternal superfecundation, leading to different blood types. Each parent contributes one blood type allele, which can result in different blood types among siblings.
Odds are one of the tests were mixed up or done improperly. Have her get retested by her Dr to make sure. Also could the genes be a factor? + blood could be dominant, - recessive and the daughter could have had dominant and recessive genes for blood types, and her boyfriend could be recessive or dominant and recessive, so when their DNA mixed, the result could have been double recessive.?
