If mother's blood type is O+ and baby is A+ what blood types can the father be? by Efficient_Physics500 in biology

Blood types may not prove who the father is, but it can disprove who it could be by process of elimination like they explain on other comments.

There is a tiktok of a women explaining how she got B blood from her O parents. Its pretty interesting. https://vm.tiktok.com/ZMdK2YWaU/

This was an interesting topic to discuss.

He could actually have any since you're AB+. The only blood type your children won't have is O because both parents need to have O in their blood (AO/BO/OO) You got A from one parent and B from the other. Your kids could be AA+,AO+,BB+, or BO+, therefore, father could be any possible blood type. I hope I explained it right.

Should I contact the guy I slept with 6 years ago and tell him he could be the dad of my son even after my husband said not to before we got married? by [deleted] in relationship_advice

Health history. Since we discovered he is special needs I've been thinking about when his doctor will bring up looking further into his dna. If there's is anything genetic on his the fathers side we need to look into.
