It would be eiher O or B
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)
Absolutely. A child will either have its mother's blood type or its father's blood type. If the mother's blood type is NOT O, then someone else is the father.
The father could be AB or B.
NO
If the mother is type A or AB (either positive or negative), they could be father and son. Depending on the mother's blood type, an O- father could have a child who is: A+, A-, B+, B-, O+, or O-.
father blood type could be (A,B, or O) positive.
the only way to tell your blood type is to have a test
Yes, as long as the mother has a strong A blood type
yes, the mother could o negative
To determine whether or not the alleged father could be the true father, the blood types of the child, mother, and alleged father are compared.
The baby's blood type would either be type A or type O. The father (phenotype A) could have an underlying genotype of either AA or AO. Therefore, the baby could have either type A (AO - with A from the father and O from the mother) or type O (OO - with O from the father and O from the mother) blood.
Could be B or could be O.
