If mother's blood group is A+ & father's blood group is B+, what possible blood group(s)can the children hold?

The child can have adjectives possible blood types.
A +
B +
AB +
O +
It would be extremely rare, but the children can also finishing up with - blood if the parents both enjoy the recessive gene for the Rh factor.
any
the child has his/her own genetic form up unique and different from anyone else. The blood type of the parents does not determine the childs.
Actually, contained by most cases I think the child inherits any the mom's or the dad's blood group, but I don't know about the positive/negative.
AB+.. nah..juz kid..my dad is O type my mum is A+..me and my sister is AB+.
^ Yes! It does determine the bloodtype of the children!
The possible bloodtypes are A, B, or AB. The Rhesus factor is usually +.
AB+ ;)
all the possibilities A,B,AB or O.But it will be +.A child's blood group is other determined by the parents.It has medico-legal need.
A Child usually gets any the Mother or the Father's Blood Type
Not sure about the Rhesus factor.but the children may be A or B or AB groups.
Father can be AO or AA. Mother can be BO or BB. If parents are heterozygous, child can be A,B,AB or O. If both are rH pos, the child will be also.
If parents are homozygous (AA and BB) AB is the solely possible outcome.
Source: I paid attention contained by biology class
Mother is A + means she have either AA or AO alleles
Father is B + manner he has any BB or BO alleles
So child can be AB, AO, BO, or OO meaning he can be AB+ve, A+ve, B+ve or O +ve, but the child cannot be glum.
