<font size="4">In between it is really not possible biologically. AB+ for one child and O- for the other is absolutely not possible</font>

<font size="4" color="#0000ff">AB consist to all the blood component and O is exactly opposite. And again + and - is another disy situation.</font>

Actually.. if d genes r A andO / A and A den d blood group of d person wl be A.. in dat case if parents have AO and BO, den der r chances fr offspring to have all d groups..AO,BO, AB n OO.. So it is possible.. i dunno if i explained it properly.. hope u got d concept.. :-) :-D

oh then the combination i wrote is correct right? n thanks😃

Yeah it is possible...depends on the alleles of their blood group genes :-)

Its possible but very rare !!!!

It can happen. One parent must have A gene and O gene and rh+ and rh- while the other parent can have B gene and O gene and rh+ and rh-. In this case the blood groups possible are A+, A-, B+, B-, AB+, AB-, O+ and O-. In short this combination gives all blood groups a rise.

Thanks yes if the genotype of parents is A/O pos/neg and B/O pos/neg; A/O neg/neg and B/O pos/neg or and or vise versa for Rh typing the child can be AB pos/pos or AB pos/neg and O neg/neg. Nice for making me remember again my genetics.

guys,...i dont know if this will help but my

Anjali like me inherited the dominant allele from each parent (A and B), while Arnav like my brother received the recessive O from each parent

my father and my blood group is O positive.my mother,my brother and my sisters blood group is A positive.

It is possible for have different blood groups amongst the sibling.

My fathers was O +ve and I'm O-ve

My mother is B -ve and brothers is B +ve
